The study analyzed and compared the effectiveness of three rating scales in the assessment of upper basic science students’ practical skills in Ekiti State. The study sample consisted of 280 (male and female) students, which were selected from five junior secondary schools in Ekiti State using multi-stage sampling techniques. Two null hypotheses were formulated and tested p = 0.05 level of significance by using the analysis of covariance and student t-test for independent data, while turkeys HSD post HOC comparison was carried out on the ANCOVA results to determine the comparative nature of the rating scales. However, findings showthat there was a significant difference in the practical skills of upper basic science students assessed with numerical, Likert and graphic rating scales. The group assessed with numerical rating scales had the best performance in practical skills. Students’ gender and school type did not significantly affect students’ practical skills in basic science. Consequently, observational techniques should hence forth be employed in assessing basic science students’ practical skills.
