The tutorial program provides in-school, individualized instruction for interstate, intrastate, and resettled migrant children residing in Ulster, Orange, Saratoga, Dutchess, and Sullivan counties. Individualized diagnostic prescriptive mathematics instruction is provided utilizing the I.M.S. Mathematics System which has 96 units and 493 specifically defined skills as the basic instructional component. Each child's tutorial instruction results from diagnostic data provided by the I.M.S. system and, in most cases, from close consultation between the tutor and the classroom teacher. Thus, the mathematics skills acquired by the children supplement and augment the skills taught during the classroom instruction. From September 1975 to April 1976, 443 migrant children in grades K-12 were provided tutorial instruction by 27 trained tutors. Involved in 14,887 tutorial instructional sessions, these children acquired a total of 1,178 specifically defined I.M.S. skills. Data indicate that on a migrant category and program-wide basis, migrant children are acquiring specific competencies in mathematics and that these competencies are in addition to the skills they would have acquired if they did not receive tutorial instruction through the New Paltz Regional Tutorial Program.
