Abstract. The aims of this study is to produce test instrument items decision-problem solving skills related to the content of Heat Transfer. The construction of the test instrument is done using scafolding construction of test items which include stages: description of indicator of decision-problem solving skills, operationalization of indicators, construction of items scenarios, writing of test items, validation of test items, and test of reliability. Validation of test items is done through construct validation by two experts namely education evaluation experts and physics expert. Test of reliability was carried out by involving 35 students of physics education program at one of the universities in South Sulawesi province. The results of expert validation of the decision-problem solving test items stated that the constructed items had high validity, and the results of the test reliability showed that the constructed test instruments had a high degree of consistencypermanence. These results indicate that the product of decision-problem solving test instrument is worthy of being used for measuring decision-problem solving skills for students of Physics education programs who contract Basic Physics courses.
