Abstract

Literature showed that there are low enrolments of students into Biology related courses such as medicine, pharmacy, radiography, nursing, dentistry and so on as result of students’ poor performances in biology and inadequate use of method of evaluation. The purpose of the study was to investigate into the criterion related validity as a correlation of student’s reliability in biology essay test scores in secondary schools. The design of the study was correlation and the population was all the 1750 biology students of the senior secondary school two (SS 2) in the 2015/2016 academic session. Simple random sampling (battling without replacement) was used to sample 450 students from 14 secondary schools in Ezeagu Local Government area of Enugu Slate. The instrument for data collection was biology essay test (BET). Pearson ‘r’ and t-test were used to correlate and test the hypotheses at 5% level of confidence. Based on the analyzed data, it was found out that the correlation coefficient value was both positive and high for the concurrent and predictive validity in essay test scores. The reliability was significant for predictive and current validity in Biology essay tests. Some recommendations were made based on the findings of the study.
