Initiated in the mid-sixties under Title I of the Elementary and Secondary Education Act, the Uniform Migrant Student Record Transfer System (UMSRTS) was designed to maintain ready accessibility via computer data base to the health and academic records of migrant children. The National Committee on the Education of Migrant Children (NCEMC) maintains that it is unwise to assume mere existence of UMSRTS either validates the system or assures its usefulness as an educational tool. The committee raises serious questions relative to: UMSRTS's detraction from development of other needed programs; its cost-effectiveness; the value of its information; evidence of its benefit, harm, or usefulness to both the child and the educational system; violation of the right to privacy; parental evaluation of data input. A recent study authorized by Congress has indicated that while the system has not worked well technically, a majority of the schools enrolled in the system have found it useful. However, a sizeable number of teachers in those same schools did not find it useful or were reluctant to rely on another's assessment of their students. The committee maintains serious reservations about the present and potential use of UMSRTS, urging extreme security relative to the right of privacy, staff development as a first priority, and further evaluation of UMSRTS.
