Assessment is an essential aspect of effective instruction. Assessment of students' performance, attitudes, perceptions, and others is observed using standard tests. In the Philippines, although the medium of instruction is English, most high school students show low competence in this subject. Thus, there is a strong possibility that their scores in assessments administered in English do not reflect the actual values. This study involves translating the Colorado Learning Attitude about Science Survey (CLASS), determining its psychometric properties, and identifying different factors that describe the students' attitude towards learning Physics. CLASS was translated into the Filipino language using direct and conceptual translation. Filipino teachers and Physics experts validated this first version based on the translation's semantics, grammar, and syntax. Another translation was done after the initial revision considering conceptual equivalence. After a successful pilot testing to 28 STEM- students of the final version, the Filipino CLASS was administered to 679 STEM students from representative public high schools in Metro Manila. Confirmatory factor analysis showed a difference in the structural model of original CLASS and Filipino CLASS. Further factor analysis identified a different factor model that would fit Filipino CLASS. The removal of non-categorical and non- correlational items finalized the factor model. The final structure model comprises four categories: Problem Solving- and Learning, Personal Interest and Real World Connection, Sense-Making/Effort, and Applied Conceptual Understanding. The result showed that the Filipino translation done in CLASS had different factors that affect students' learning attitudes towards Physics.
