Critical thinking is a key learning outcome for Palestinian students. However, there are no validated critical thinking tests in Arabic. Suitability of the US developed Critical Thinking Assessment Test (CAT) for use in Palestine was assessed. The test was piloted with university students in English (n = 30) and 4 questions were piloted in Arabic (n = 48). Students responded favorably. Scores were comparable with US scores. Only two students found the content problematic. One-hundred-twelve Palestinian faculty reviewed the skills tested by the CAT. There was moderate agreement that they represent critical thinking. Translation of the CAT into Arabic and further study are warranted.
