The study used descriptive research design utilizing adapted questionnaire-checklist to determine the level of acceptability of the worktext; experimental research design to test the work text’s effectiveness with two groups of student respondents equated in terms of sex and final grade in College Algebra gathered through documentary analysis; and, Spearman rho, mean and t-test to statistically treat gathered data. Content-validated pretest/posttest underwent item analysis to determine difficulty and discrimination index; and, the test-retest method for its reliability index. The study found the pretest/posttest valid and reliable; there’s a significant difference on the performance level of respondents in all learning areas as revealed by their pretest and posttest mean; no significant difference on their performance level as revealed by their posttest mean; in the seven learning areas of the work text, it is more effective in three areas; equally effective in one area as revealed by the mean increments; and, the work text as an instructional material of exemplary acceptability.
