Students in an Ohio community (363 males and 332 females) took the Iowa Test of Basic Skills in the spring of their eighth-grade year and the Ohio Ninth Grade Proficiency Test (ONGPT) in the following fall of their ninth-grade year. The scores from both tests, for a period of 3 consecutive years, were correlated to determine the predictability of passing or failing the ONGPT, based on the standardized test scores. The correlations were found to be significant for reading, mathematics, writing, and citizenship. It was also shown that the percentages of students failing the ONGPT who scored below the third stanine were high in three areas (reading--60 percent, mathematics--93 percent, and citizenship--90 percent). Therefore, stanine scores can be helpful predictors of the need for intervention programs. Three tables present study findings. (Contains 4 references.) (Author/SLD)
