The New York City high schools participating in the 1989/90 Peer Tutoring Program demonstrated excellent performance in reaching program objectives. The Peer Tutoring Program serves high school students who have failed to achieve specified levels of achievement in mathematics, reading/writing, or English as a Second Language. Higher-achieving students provide tutoring in one-to-one or small group sessions either before or after school. A few schools also provided in-classroom tutorials. The program is funded in low-income schools by Chapter 1 of the Education Consolidation and Improvement Act and in other schools by New York State's Pupils with Compensatory Educational Needs (PCEN) Program. Sixty-two of the 71 participating schools responded with evaluation information on 721 tutors and 7,492 students. Ninety-seven percent of the schools met the first objective of at least 25 students participating in the before- or after-school programs. The program as a whole met the second objective of at least 50 percent of the participants in the before- and after-school programs participating for at least 9 hours of instruction, and the third objective of at least 70 percent of the participants in classroom tutorials passing the class in which they were being tutored. Eighty percent of the schools met the fourth objective of training at least five tutors. Many of the schools expressed interest in implementing computer-assisted tutorial instruction in future programs. Statistical data are presented in three tables. (FMW)
