This study aimed to determine the procedures and quality of developing test instruments to measure student mathematical communication skills of SMP Negeri 17 Makassar. The research type used research and development with the Plomp model through 4 stages: preliminary investigation, design, realization/construction, test, evaluation, and revision. The results showed that the developed test instrument was valid with a high interpretation from the value of CVR and CVI is 1. The instrument test was reliable on 0.71 with a very high interpretation while in terms of the level there was 1 item in the difficult category, 7 items in the medium category and 1 item in the easy category. In terms of distinguishing power, there were 2 items at sufficient categories, 3 items in the good category, 2 items in very good categories and 2 items in the poor category. Therefore, the test instruments that met the quality of the criteria from the good test instruments consists of 5 items of description questions. Moreover, based on the results of the trial, it is known that from 32 students there were 4 students categorized who had a very good level of mathematical communication skills, 9 students included in the good level of mathematical communication skills, 17 students under sufficient level of mathematical communication skills, and 2 students in the less level of mathematical communication skills.
