This study attempted to develop fair, relevant, and content-valid assessment tools for capstone project courses. Toward this goal, new rating instruments based on the concept of rubrics were proposed. To ensure that the new instruments were valid and fair, several meetings with faculty and students of the computing science departments (i.e., Computer Science and Information Technology) were successively conducted. Eight faculty members and 10 students participated in the study. The final versions of the instruments were completed after a series of careful deliberations with faculty and students. Faculty and students perceived the new instruments fairer than the previous ones. Since the final instruments will be deployed this semester, their strengths and weaknesses are not yet known at this time. Directions for future research are presented.
