This study aims to develop an assessment instrument to measure the multi-representation physics skills of senior high school students in grade X on simple harmonic motion material. The method used is instrument development by Djemari Mardapi, (1) Determination of test objectives (2) Determination of material to be tested (3) Arrange the test grid (4) Write item’s Question (5) Validate test item, (6) Determination of Test Subjects (7) Test Implementation (8) Analyze Test Question. Based on the result validation of two expert judgement the Aiken’s V index value of 10 items are in the range of 0.85-0.91, according to Aiken’s V > 0.8 validation included in the very high classification. The level of difficulty in instrumen is good category between -1.53 up to 1.04. and the instrument reliability of 0.84 the assessment instrumen multi-representation skills are classified as very high category.
