TWO NEW TESTS WERE DEVELOPED IN THE INTER-AMERICAN TEST SERIES IN PARALLEL ENGLISH AND SPANISH EDITIONS. A PRESCHOOL TEST WAS ADDED TO THE TESTS OF GENERAL ABILITY AND A LEVEL 1 TEST ADDED TO THE TESTS OF READING. ALSO THE SPANISH EDITIONS OF SOME EARLIER TESTS WERE REVISED AND ADDITIONAL INTERPRETATIVE MATERIALS DEVELOPED. THE AUTHOR BELIEVED THAT THE NORMS OF THE TESTS ALREADY CONSTRUCTED SHOULD BE STRENGTHENED BY ADDITIONAL TESTING OF REFERENCE GROUPS. RELATED REPORTS ARE ED 001 702 AND ED 003 857. (TC)
