This study was designed to investigate the effects of speed, power and mastery (time limit) tests on SS 1 students’ achievement in Biology. The researcher adopted a non-equivalent quasi-experimental design. A sample of 378 SS 2 students was drawn from the three schools in Enugu education zone of Enugu State. In each of the three school used one intact class was randomly drawn, one intact class was then randomly assigned to the experimental groups 1, II and the other intact class was assigned to conventional group 111.

The three groups were examined using speed, power and mastery tests for experimental group I (speed,), experimental group II (power) and conventional group 111 (mastery tests). A research question and a hypothesis guided the study.

Relevant data for the study were collected using Biology Achievement Test (BAT). Research question was answered using mean and standard deviation while hypothesis was tested using Analysis of Covariance (ANCOVA). The results showed that the use of speed test in evaluating Biology in secondary schools was found to achieve higher than those using mastery test and power tests/conventional whereas the use of mastery tests was found to be better than the use of conventional/ power tests in evaluating biology. Some recommendations were made based on the findings of the study.
