The process Assessment of the Learner-Second Edition: Diagnostic Assessment for Math is one of the most widely used tests in the field of learning disorders, which has two versions: reading, writing, and math. The purpose of the present study was to investigate the educational and cultural adaptation of this test. For this purpose, after the translation of the test, the stages of cultural adaptation were investigated from three sources of elementary school mathematics textbooks, interviews with teachers and test implementation of the test on a group of 14 children from preschool to sixth grade, applicability and Special criteria for the implementation of the test were prepared for Iranian students. There has been an amendment to the content of the Iranian sample test in terms of the items of multi-step problem-solving and part-whole concepts. Also, the criteria for passing the test for Iranian students in the sub-tests of place value, finding the bug, and the ability to perform calculations are placed at a higher age than the main instructions of the test. Geometry and decimal numbers are items that are covered in the Pal_II math test in the form of part_whole concepts. However, it is more detailed and complicated in Iranian math textbooks. Calculation education in Iran's school education system has undergone changes in recent years, which were revised in the test instructions. The similarities between the implementation and grading of the Persian version of the Pal_II math test in the Iranian sample and the original instructions of the English version of the test are more than the differences between them.
