THE ILLINOIS TEST OF PSYCHOLINGUISTIC ABILITIES, A TEST DESIGNED FOR CHILDREN AGED 3-9, IS OF VALUE TO THE KINDERGARTEN OR FIRST-GRADE TEACHER IN DIAGNOSING FOR THE PURPOSE OF REMEDIATION, ESPECIALLY IN COMMUNITIES WHERE DISADVANTAGED AREAS EXIST. FROM ITS USE, THE TEACHER CAN DETERMINE BACKGROUND INADEQUACIES, DIFFERENCES BETWEEN THE LEVEL OF A CHILD'S IDEAS AND HIS ABILITY TO EXPRESS THEM, DEVIATIONS IN AUDITORY AND VISUAL ABILITIES, DEGREES OF SELF- CONFIDENCE IN LANGUAGE USAGE, DIFFERENCES IN HEARING AND SPEAKING VOCABULARIES, AND ARTICULATION PROBLEMS. TEST RESULTS ALLOW THE TEACHER TO CREATE PROGRAMS THAT DEVELOP READING READINESS ON THE BASIS OF INDIVIDUAL NEEDS. THIS PAPER WAS PRESENTED AT THE INTERNATIONAL READING ASSOCIATION CONFERENCE (BOSTON, APRIL 24-27, 1968). (BS)
