This study intended to develop the Countenance model evaluation instruments that were integrated with the Tri Kaya Parisudha concept as a blended learning evaluation tool for Tourism Vocational Schools in Gianyar Regency. This study approach was the instrument development, by several development stages, including evaluation components determination, evaluation aspects determination, instrument items determination, instrument items trial, instrument items analysis, and final items determination. The instruments which were used in data collection were questionnaires and documentation. Subjects those were involved in instrument trial on the content validation process were two experts (experts in informatics engineering education and educational evaluation), while the reliability testing process were 48 respondents (teachers and students). The instruments analysis technique during the content validation process used the Gregory formula, while during the reliability test process using the Cronbach Alfa formula. This study produced 122 items with very high validity and very high reliability categories, as evidenced by the r-scores of 0.938 and 0.961, respectively.
