Assessment in learning is an important aspect to analyze the learning progress. Nowadays, the assessment runs a shifted paradigm from measuring in higher-order thinking aspects to performance assessment. This study aims to develop an assessment instrument based Authentic Scienti-c Inquiry Assessment (ASIA) in measuring the laboratory skills. The laboratory skills consist of-ve skills categories, they are safety skills in the laboratory, experiment management, measuring skills, collecting data, and interpreting skills. From those skills, we derive 20 aspects. We used 4D methods in developing the instruments, define, design, develop, and disseminate. The results of construct validation and content show that the instrument is valid and reliable. We perform the effectivity test and gain the tcount = 25281; ttable = 1,708 with significance level less than 0,05. We also perform a questionnaire for the lecturers and laboratory assistant that shows 85% positive response, 11% of negative response, and 4% of abstance. We can conclude that our instrument is effective to measure the laboratory skills. © Published under licence by IOP Publishing Ltd.
