The Development and Validation of Standardized Test in Advanced Algebra is designed for students of Ilocos Sur Polytechnic State College. Three research questions guided the study. The standardized test in Advanced Algebra was constructed using table of specification, outcomes based education syllabus, compilation of test questions as well as validation through the five Math experts. Internal consistency method was employed for its reliability. It was administered to 33 BSEd Mathematics major using an 80-item test and was trimmed down to 45 items. The validity index, index of difficulty and discrimination power was used to accept, reject and revise the test items. Kuder – Richardson 20 was used for the reliability. Recommendations were made that the standardized test can be used to assess student’s performance from time to time.

                The aim of this study is to develop and assess the validity and reliability of the instrument to evaluate the performance of students. The test was distributed to all the third year BSEd Math majors who had already taken the subject Advance Algebra. The validity of the test instrument was assessed by the five math experts. The reliability of the instrument was measured using the internal consistency reliability method. The findings of this study shows that the test instrument was valid and reliable. Finally, out of 80 items, 45 items were retained.
