Abstract                This study aimed to develop an item bank for testing and diagnostic assessment program of problem solving skills in application of linear equation. The samples were 1,266 lower secondary students in Secondary Educational Service Area 32, Buriram province, Thailand of academic year 2017. They were chosen by two-stage random sampling method. Research tools used in the study were two tests which were a completion test for survey and a 5-choice test of problem solving skills in application of linear equation. Parameter of the test was analyzed according to Item Response Theory by BILOG-MG program and calibrated test parameter by means and sigma methods before choosing for an item bank. Results revealed that 48 items selected for the item bank included proper level of difficulty for mearing skills from easy to difficult. Moreover, ration of the test in the stages of understanding the problem, devising a plan, carrying out the plan, and looking back were 8:9:17:14 items. It also found that items in the item bank had a good level of parameter which contained high discrimination, moderate to hard test difficulty, and low guessing possibility. Besides, an item bank was created by PhpMyAdmin, a data base management system program, which included data of pictures, letters, and numbers. By trying out recoding data, it showed that the program was appropriate to be used as a database for developing a testing and diagnostic assessment program of problem solving skills which it could add or delete test items or test details dramatically.
