Science education instrument is one of the determinants of quality output in the production of scientists for
technological emancipation of a nation. It provides feedback on learning for knowledge and skills acquisition
towards award of a certificate of proficiency and competence. However, the rate of graduate unemployment had
been on a steady increase over the last two decades. As a result of low quality of certificated outputs. Therefore,
the paper examines processes of constructing and validating a reliable instrument for measuring cognitive
learning outcomes in science education in colleges of education in Nigeria. Also, it identifies features of a good
question paper and marking guide/scheme as complementary components in the assessment of students’ academic
growth. Recommendations were made towards ensuring a valid and reliable quantification of students’ cognitive
achievement in science education.
