This philosophical value needs to be strengthened and maintained amongst students as part of character education. Therefore, an assessment instrument of the character wasaka was developed to help teachers measure the values of religious, sincere, hard work, resilience, honesty, and persistence in students. This article aims to describe the validation of the contents of wasaka character through assessment instrument as carried out using expert judgment method. There are 35 statement items assessed by 13 validators. Each statement item is examined by five assessment categories included in the expert validation sheets. The results of the assessments were analyzed using Aiken’s V equation to determine the level of validity of each statement item. With a validity standard of 0.75, there are 29 valid items and six invalid items. Furthermore, valid statements will be tested on students to determine the reliability of their measurements.
