Popis:	A computer algorithm which links student test records using information available on two files is described and data on its accuracy presented. During the past four years it has been used to match over 1.6 million student records for use in a statewide school reward program. The results indicate that after minimal editing about .18 percent of the computer matches were incorrect and .44 percent of the potential valid matches were missed. By comparison, matches based on unedited student ID numbers produced almost no mismatches (.06%) but missed about 6 percent of the possible matches. For many applications the computer error rates should be tolerable and, since the system utilizes extant data, it is clearly cost-effective. A number of additional areas of application are described.
