This research focused on the development and validation of a test for Grade Seven students that can used to assess and monitor acquisition and development of Science Process Skills. A framework with eight Science Process Skills, each with three sub-skills, was developed based on a review of extant literature and following the K to 12 Science Education Framework of the Philippines. The eight Science Process Skills were: (1) observing, (2) inferring, (3) measuring, (4) classifying, (5) predicting (6) conducting scientific investigations (7) interpreting data, and (8) communicating. The test development and validation process followed guidelines from the Standards for Educational and Psychological Testing of the American Educational Research Association, the American Psychological Association, and the National Council of Measurement in Education. Psychometric analysis using both classical test statistics and Item Response Theory showed that the instrument was internally consistent, reliable, and did not function differentially for male and female students.
