The Program for Institutionalized Children in New York City provided reading and/or mathematics instruction for 624 Title I eligible pupils in grades one through twelve in 12 institutions for neglected, abused, or delinquent children. The program operated for seven weeks with approximately 15 hours of instruction weekly. Small group instruction or individual tutoring was provided by 80 teachers assisted by 12 paraprofessionals and three student aids under the supervision of eight teachers-in-charge. All students were given entry and mastery tests with standardized criterion-referenced tests from the Croft reading system and/or from the Base mathematics system. The major evaluation objective of having 70% of the participants demonstrate mastery of at least two instructional objectives in reading and/or mathematics was achieved. In reading, 75% of the pupils achieved mastery of at least two objectives as a result of instruction. In mathematics, 86% of the pupils mastered at least two objectives as a result of instruction. Sixty-eight percent of the pupils demonstrated mastery of more than 70% of the instructional objectives they attempted in both subject areas. (Author/AM)
