            The purposes of this research were to develop a testing and diagnostic assessment program of problem solving skills in application of linear equation. It carried out processes and development into 3 stages which were item bank development, program creation and trial, and quality assessment of the program, respectively.                 

            The research findings were as follows: the program included item bank of application of linear equation for 48 items. The program was able to estimate test takers’ abilities in term of correction frequency based on 4 stages of problem solving skills process which included understanding the problem, devising a plan, carrying out the plan, and looking back. It clarified test takers’ abilities into 5 levels: very good, good, average, poor, and very poor. Finally, after trying out with teachers and students and its quality evaluation from their usage, teachers considered the program with utility, feasibility, propriety, and accuracy were at the highest level while the students’ perceptions of the program in terms of utility, feasibility, propriety, and accuracy were at high level.
