 It's summertime, but thousands of New Haven students are still heading to school every day. The city is offering multiple programs, the biggest in the Summer Learning Academy. It's for students from kindergarten to eighth grade. Studies show that summer vacation can cause students to forget knowledge and skills they learned during the school year. Educators call it the summer slide. The Learning Academy is taking place in 10 different locations this summer. That's up from six. The city also runs a summer bridge program for rising ninth graders to get them prepared for high school.
