This volume summarizes information provided by state education agencies on student achievement in Chapter 1 Migrant Education Programs. For the regular term, 34 states (out of 48) provided statewide achievement information using norm-referenced tests (29 states), criterion-referenced tests (8 states), and locally developed instruments (1 state). For the summer term, 14 states (out of 47) provided statewide achievement information. Several underlying factors affect the assessment of achievement outcomes in migrant education programs. The most important are the lack of standardized reporting requirements for achievement, tendency for currently migrant students to be underrepresented due to mobility and language deficits, incompatibility of standardized test schedules with the short-term nature of many migrant projects or the cyclical patterns of migrant movement, and a poor match between testing and services received. This report presents summary findings for those states reporting regular-term achievement results, expressed in normal curve equivalent scores, using a pre- and posttest norm-referenced model. Such data were reported for about 30,000 migrant students in 16 states tested on an annual cycle in reading and for slightly over 17,000 tested in mathematics, and for over 2,800 students in 9 states tested on a fall-spring test cycle in reading and for slightly over 2,000 students in 10 states tested similarly in mathematics. Following summary information, individual state information includes enrollments, services provided, and achievement results. Includes extensive data tables. (SV)
