opinion: Chief Justice Burger
  delivered the opinion of the Court.
  We granted certiorari to decide whether a private school, whose income is derived primarily from public sources and which is regulated by public authorities, acted under color of state law when it discharged certain employees.

  A
  Respondent Kohn is the director of the New Perspectives School, a nonprofit institution located on privately owned property in Brookline, Massachusetts. The school was founded as a private institution and is operated by a board of directors, none of whom are public officials or are chosen by public officials. The school specializes in dealing with students who have experienced difficulty completing public high schools; many have drug, alcohol, or behavioral problems, or other special needs. In recent years, nearly all of the students at the school have been referred to it by the Brookline or Boston School Committees, or by the Drug Rehabilitation Division of the Massachusetts Department of Mental Health. The school issues high school diplomas certified by the Brook-line School Committee.
  When students are referred to the school by Brookline or Boston under Chapter 766 of the Massachusetts Acts of 1972, the School Committees in those cities pay for the students’ education. The school also receives funds from a number of other state and federal agencies. In recent years, public funds have accounted for at least 90%, and in one year 99%, of respondent school’s operating budget. There were approximately 50 students at the school in those years and none paid tuition.
  To be eligible for tuition funding under Chapter 766, the school must comply with a variety of regulations, many of which are common to all schools. The State has issued detailed regulations concerning matters ranging from record-keeping to student-teacher ratios. Concerning personnel policies, the Chapter 766 regulations require the school to maintain written job descriptions and written statements describing personnel standards and procedures, but they impose few specific requirements.
  The school is also regulated by Boston and Brookline as a result of its Chapter 766 funding. By its contract with the Boston School Committee, which refers to the school as a “contractor,” the school must agree to carry out the individualized plan developed for each student referred to the school by the Committee. See n. 1, supra. The contract specifies that school employees are not city employees.
  The school also has a contract with the State Drug Rehabilitation Division. Like the contract with the Boston School Committee, that agreement refers to the school as a “contractor.” It provides for reimbursement for services provided for students referred to the school by the Drug Rehabilitation Division, and includes requirements concerning the services to be provided. Except for general requirements, such as an equal employment opportunity requirement, the agreement does not cover personnel policies.
  While five of the six petitioners were teachers at the school, petitioner Rendell-Baker was a vocational counselor hired under a grant from the federal Law Enforcement Assistance Administration, whose funds are distributed in Massachusetts through the State Committee on Criminal Justice. As a condition of the grant, the Committee on Criminal Justice must approve the school’s initial hiring decisions. The purpose of this requirement is to insure that the school hires vocational counselors who meet the qualifications described in the school’s grant proposal to the Committee; the Committee does not interview applicants for counselor positions.
  B
  Rendell-Baker was discharged by the school in January 1977, and the five other petitioners were discharged in June 1978. Rendell-Baker’s discharge resulted from a dispute over the role of a student-staff council in making hiring decisions. A dispute arose when some students presented a petition to the school’s board of directors in December 1976, seeking greater responsibilities for the student-staff council. Director Kohn opposed the proposal, but Rendell-Baker supported it and so advised the board. On December 13, Kohn notified the State Committee on Criminal Justice, which funded Rendell-Baker’s position, that she intended to dismiss Rendell-Baker and employ someone else. Kohn notified Rendell-Baker of her dismissal in January 1977.
  Rendell-Baker then advised the board of directors that she had been discharged without due process because she exercised her First Amendment rights. She demanded reinstatement or a hearing. The school agreed to apply a new policy, calling for appointment of a grievance committee, to consider her claims. Rendell-Baker also complained to the State Committee on Criminal Justice, which asked the school to provide a written explanation for her discharge. After the school complied, the Committee responded that it was satisfied with the explanation, but notified the school that it would not pay any backpay or other damages award Rendell-Baker might obtain from it as a result of her discharge. The Committee told Rendell-Baker that it had no authority to order a hearing, although it would refuse to approve the hiring of another counselor if the school disregarded its agreement to apply its new grievance procedure in her case. At this point Rendell-Baker objected to the composition of the grievance committee, and its proceedings apparently never went forward. Rendell-Baker filed this suit in July 1977 under 42 U. S. C. §1983, alleging that she had been discharged in violation of her rights under the First, Fifth, and Fourteenth Amendments.
  In the spring of 1978, students and staff voiced objections to Kohn’s policies. The five petitioners other than Rendell-Baker, who were all teachers at the school, wrote a letter to the board of directors urging Kohn’s dismissal. When the board affirmed its confidence in Kohn, students from the school picketed the home of the president of the board. The students were threatened with suspension; a local newspaper then ran a story about the controversy at the school. In response to the story, the five petitioners wrote a letter to the editor in which they stated that they thought the prohibition of picketing was unconstitutional. On the day the letter to the editor appeared, the five teachers told the president of the board that they were forming a union. Kohn discharged the teachers the next day. They brought suit against the school and its directors in December 1978. Like Rendell-Baker, they sought relief under §1983, alleging that their rights under the First, Fifth, and Fourteenth Amendments had been violated.
  C
  On April 16, 1980, the District Court for the District of Massachusetts granted the defendant’s motion for summary judgment in the suit brought by Rendell-Baker. A claim may be brought under §1983 only if the defendant acted “under color” of state law. The District Court took as its standard “‘whether there is a sufficiently close nexus between the State and the challenged action of the regulated entity so that the action of the latter may be fairly treated as that of the State itself,'” quoting Jackson v. Metropolitan Edison Co., 419 U. S. 345, 351 (1974). Noting that, although the State regulated the school in many ways, it imposed few conditions on the school’s personnel policies, the District Court concluded that the nexus between the school and the State was not sufficiently close so that the action of the school in discharging Rendell-Baker could be considered action of the Commonwealth of Massachusetts.
  Nine days earlier, on April 7, 1980, a different judge of the District Court for the District of Massachusetts had reached a contrary conclusion on the same question in the case brought by the other five petitioners. His opinion stressed the school’s dependency on public funding and its regulation by numerous public entities. It also noted that although education was not a uniquely public function, it is primarily a public function, and that Brookline did not maintain a school to serve maladjusted adolescents with drug, alcohol, or emotional problems. The District Court, following the guidelines of Burton v. Wilmington Parking Authority, 365 U. S. 715, 722 (1961), concluded that the school performed a “public function,” as described in Jackson, supra, at 352. Accordingly, it held that the defendants acted under color of state law and denied the motion to dismiss. However, on June 13, 1980, noting that there was substantial ground for disagreement on that holding, the District Court certified its order as immediately appealable pursuant to 28 U. S. C. § 1292(b).
  D
  The Court of Appeals for the First Circuit consolidated the two actions. It noted that the school’s funding, regulation, and function show that it has a close relationship with the State. However, it stressed that the school is managed by a private board and that the State has relatively little involvement in personnel matters. It concluded that the school, although regulated by the State, was not dominated by the State, especially with respect to decisions involving the discharge of personnel. The Court of Appeals then concluded that the District Court which certified the question in the action brought by the five teachers had erred in concluding that the defendants acted under color of state law.
  The Court of Appeals separately considered Rendell-Baker’s claim that she was discharged under color of state law since her position was funded directly by the Committee on Criminal Justice. The court rejected her claim, noting that the Committee had the power to insure that those hired had the qualifications described in the grant proposal, but that it did not have any other control over the school’s personnel decisions. It therefore affirmed the District Court’s dismissal of her action. 641 F. 2d 14 (1981).
  We granted certiorari, 454 U. S. 891 (1981), and we affirm.

  A
  Petitioners do not claim that their discharges were discriminatory in violation of Title VII of the Civil Rights Act of 1964. Nor do they claim that their discharges were unfair labor practices in violation of the National Labor Relations Act. Rather, they allege that respondents violated 42 U. S. C. § 1983, see n. 4, supra, by discharging them because of their exercise of their First Amendment right of free speech and without the process due them under the Fourteenth Amendment. Although Title VII and the National Labor Relations Act govern action by private parties making personnel decisions, it is fundamental that the First Amendment prohibits governmental infringement on the right of free speech. Similarly, the Fourteenth Amendment, which prohibits the states from denying federal constitutional rights and which guarantees due process, applies to acts of the states, not to acts of private persons or entities. Civil Rights Cases, 109 U. S. 3, 11 (1883); Shelley v. Kraemer, 334 U. S. 1, 13 (1948). And § 1983, which was enacted pursuant to the authority of Congress to enforce the Fourteenth Amendment, prohibits interference with federal rights under color of state law.
  In United States v. Price, 383 U. S. 787, 794, n. 7 (1966), the Court stated:
  “In cases under § 1983, ‘under color’ of law has consistently been treated as the same thing as the ‘state action’ required under the Fourteenth Amendment.”
  See also, United States v. Classic, 313 U. S. 299, 326 (1941). The ultimate issue in determining whether a person is subject to suit under § 1983 is the same question posed in cases arising under the Fourteenth Amendment: is the alleged infringement of federal rights “fairly attributable to the State?” Lugar v. Edmondson Oil Co., post, at 937. The core issue presented in this case is not whether petitioners were discharged because of their speech or without adequate procedural protections, but whether the school’s action in discharging them can fairly be seen as state action. If the action of the respondent school is not state action, our inquiry ends.
  B
  In Blum v. Yaretsky, post, p. 991, the Court analyzed the state action requirement of the Fourteenth Amendment. The Court considered whether certain nursing homes were state actors for the purpose of determining whether decisions regarding transfers of patients could be fairly attributed to the State, and hence be subjected to Fourteenth Amendment due process requirements. The challenged transfers primarily involved decisions, made by physicians and nursing home administrators, to move patients from “skilled nursing facilities” to less expensive “health-related facilities.” Post, at 1005. Like the New Perspectives School, the nursing homes were privately owned and operated. Post, at 1003. Relying on Flagg Brothers, Inc. v. Brooks, 436 U. S. 149 (1978); Jackson v. Metropolitan Edison Co., 419 U. S. 345 (1974); Moose Lodge No. 107 v. Irvis, 407 U. S. 163 (1972); and Adickes v. S. H. Kress Co., 398 U. S. 144 (1970), the Court held that, “a State normally can be held responsible for a private decision only when it has exercised coercive power or has provided such significant encouragement, either overt or covert, that the choice must in law be deemed to be that of the State.” Post, at 1004. In determining that the transfer decisions were not actions of the State, the Court considered each of the factors alleged by petitioners here to make the discharge decisions of the New Perspectives School fairly attributable to the State.
  First, the nursing homes, like the school, depended on the State for funds; the State subsidized the operating and capital costs of the nursing homes, and paid the medical expenses of more than 90% of the patients. Post, at 1011. Here the Court of Appeals concluded that the fact that virtually all of the school’s income was derived from government funding was the strongest factor to support a claim of state action. 641 F. 2d, at 24. But in Blum v. Yaretsky, we held that the similar dependence of the nursing homes did not make the acts of the physicians and nursing home administrators acts of the State, and we conclude that the school’s receipt of public funds does not make the discharge decisions acts of the State.
  The school, like the nursing homes, is not fundamentally different from many private corporations whose business depends primarily on contracts to build roads, bridges, dams, ships, or submarines for the government. Acts of such private contractors do not become acts of the government by reason of their significant or even total engagement in performing public contracts.
  The school is also analogous to the public defender found not to be a state actor in Polk County v. Dodson, 454 U. S. 312 (1981). There we concluded that, although the State paid the public defender, her relationship with her client was “identical to that existing between any other lawyer and client.” Id., at 318. Here the relationship between the school and its teachers and counselors is not changed because the State pays the tuition of the students.
  A second factor considered in Blum v. Yaretsky was the extensive regulation of the nursing homes by the State. There the State was indirectly involved in the transfer decisions challenged in that case because a primary goal of the State in regulating nursing homes was to keep costs down by transferring patients from intensive treatment centers to less expensive facilities when possible. Both state and federal regulations encouraged the nursing homes to transfer patients to less expensive facilities when appropriate. Post, at 1007-1008,1009-1010. The nursing homes were extensively regulated in many other ways as well. The Court relied on Jackson, where we held that state regulation, even if “extensive and detailed,” 419 U. S., at 350, did not make a utility’s actions state action.
  Here the decisions to discharge the petitioners were not compelled or even influenced by any state regulation. Indeed, in contrast to the extensive regulation of the school generally, the various regulators showed relatively little interest in the school’s personnel matters. The most intrusive personnel regulation promulgated by the various government agencies was the requirement that the Committee on Criminal Justice had the power to approve persons hired as vocational counselors. Such a regulation is not sufficient to make a decision to discharge, made by private management, state action. See n. 6, supra.
  The third factor asserted to show that the school is a state actor is that it performs a “public function.” However, our holdings have made clear that the relevant question is not simply whether a private group is serving a “public function.” We have held that the question is whether the function performed has been “traditionally the exclusive prerogative of the State.” Jackson, supra, at 353; quoted in Blum v. Yaretsky, post, at 1011 (emphasis added). There can be no doubt that the education of maladjusted high school students is a public function, but that is only the beginning of the inquiry. Chapter 766 of the Massachusetts Acts of 1972 demonstrates that the State intends to provide services for such students at public expense. That legislative policy choice in no way makes these services the exclusive province of the State. Indeed, the Court of Appeals noted that until recently the State had not undertaken to provide education for students who could not be served by traditional public schools. 641 F. 2d, at 26. That a private entity performs a function which serves the public does not make its acts state action.
  Fourth, petitioners argue that there is a "symbiotic relationship” between the school and the State similar to the relationship involved in Burton v. Wilmington Parking Authority, 365 U. S. 715 (1961). Such a claim is rejected in Blum v. Yaretsky, and we reject it here. In Burton, the Court held that the refusal of a restaurant located in a public parking garage to serve Negroes constituted state action. The Court stressed that the restaurant was located on public property and that the rent from the restaurant contributed to the support of the garage. 365 U. S., at 723. In response to the argument that the restaurant’s profits, and hence the State’s financial position, would suffer if it did not discriminate, the Court concluded that this showed that the State profited from the restaurant’s discriminatory conduct. The Court viewed this as support for the conclusion that the State should be charged with the discriminatory actions. Here the school’s fiscal relationship with the State is not different from that of many contractors performing services for the government. No symbiotic relationship such as existed in Burton exists here.
  C
  We hold that petitioners have not stated a claim for relief under 42 U. S. C. § 1983; accordingly, the judgment of the Court of Appeals for the First Circuit is
  Affirmed.
  Chapter 766, 1972 Mass. Acts, Mass. Gen. Laws Ann., ch. 71B, §3 (West Supp. 1981), requires school committees to identify students with special needs and to develop suitable educational programs for such students. Massachusetts Gen. Laws Ann., ch. 71B, §4 (West Supp. 1981), provides that school committees may “enter into an agreement with any public or private school, agency, or institution to provide the necessary special education” for these students. A student identified as having special needs and recommended for placement in private school may remain in public school, if his parents object to a placement in a particular private school, unless he is especially disruptive or dangerous. Parents who object to placement in a particular private school may also elect to place their child in a private school of their choice; in such cases, they must pay the tuition.
  Amicus curiae Massachusetts Association of 766 Approved Private Schools, Inc., of which the New Perspectives School is a member, informs the Court that many of its members have a student population which is more or less evenly divided between students referred and paid for by the State and students referred and paid for by their parents or guardians. Brief as Amicus Curiae 3.
  The record does not contain details of the school’s contract with the Brookline School Committee.
  Title 42 U. S. C. § 1983 provides:
  “Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory, subjects, or causes to be subjected, any citizen of the United States or other person within the jurisdiction thereof to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured in an action at law, suit in equity, or other proper proceeding for redress.”
  The Fourteenth Amendment provides, in pertinent part:
  “No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law . . .
  The Court has concluded that the acts of a private party are fairly attributable to the state on certain occasions when the private party acted in concert with state actors. For example, in Adickes v. S. H. Kress & Co., 398 U. S. 144, 155-156 (1970), the issue was whether a restaurant violated § 1983 by refusing service to a white teacher who was in the company of six Negro students; the town sheriff arrested the white teacher for vagrancy as a result of her request to be served lunch in their company. The Court concluded that the restaurant acted under color of state law because it conspired with the sheriff, a state actor, in depriving the white teacher of federal rights.
  Similarly, Flagg Brothers, Inc. v. Brooks, 436 U. S. 149 (1978), and Lugar, post, p. 922, illustrate the relevance of whether action was taken in concert with a state actor. The issue in Flagg Brothers was whether a warehouseman could be sued under § 1983 because it sought to execute a lien by selling goods in its possession pursuant to § 7-210 of the New York Uniform Commercial Code. While the sale was authorized by a state statute, and hence appeared to be threatened under color of state law, the Court did not reach that issue. Instead, it concluded that the warehouseman’s decision to threaten to sell the goods was not “properly attributable to the State of New York,” 436 U. S., at 156, since no state actor was involved. Since the respondent in Flagg Brothers claimed that the warehouseman violated her Fourteenth Amendment rights to due process and equal protection, and the Fourteenth Amendment is only offended by action of the state, we held that no claim for relief had been stated.
  In Lugar, a lessee obtained an ex parte writ of attachment pursuant to a state statute, which was executed by a sheriff. The Court held that § 1983 applied because the involvement of the sheriff distinguished the case from Flagg Brothers. Post, at 941. The lessee thus acted under color of state law and the sheriff’s involvement satisfied the state action requirement.
  The limited role played by the Massachusetts Committee on Criminal Justice in the discharge of Rendell-Baker is not comparable to the role played by the public officials in Adickes and Lugar. The uncontradicted evidence presented by the school showed that the Committee had the power only initially to review the qualifications of a counselor selected by the school to insure that the counselor met the requirements described in the school’s grant application. 641 F. 2d 14, 28 (1981). The Committee had no power to hire or discharge a counselor who had the qualifications specified in the school’s grant application. Moreover, the Committee did not take any part in discharging Rendell-Baker; on the contrary, it attempted to use leverage to aid her. It requested an explanation for her discharge from the school and stated that it would not approve the appointment of a successor unless a grievance committee considered Rendell-Baker’s case. As the Court of Appeals correctly concluded, there is no evidence that the Committee had any authority to take even those steps. Ibid.
  There is no evidence that the State has attempted to avoid its constitutional duties by a sham arrangement which attempts to disguise provision of public services as acts of private parties. Cf. Evans v. Newton, 382 U. S. 296 (1966) (private trustees appointed to manage previously public park for white persons only).
