This study represents a further attempt to establish the long-term predictive validity of teachers' grade 1 early identification (EID) ratings by relating them to students' educational status and performance on standardized tests of ability and achievement in grade 7. (EID ratings consist of a simple scale that ranks a student's preparedness for the work of the next school year.) In addition, relationships between the measures taken in grades 4 and 7 are described. All 2,771 students who enrolled in grade 1 during the 1978-79 school year and for whom EID ratings were available were included in the study. For some analyses, only those students who were present for standardized tests in both grades 4 and 7 were included. Results indicate a substantial relationship between the grade 1 ratings and students' subsequent status and test performance in both grade 4 and grade 7. Because the study did not include test data for students who had either been retained or enrolled in a special class, the underlying strength of the relationships described has probably been somewhat underestimated. Almost 30 percent of the original grade 1 cohort left the system. Of those remaining, slightly over 80 percent made normal progress. (RH)
