Scale for Coordinate Contiguous Career (Scale C3) was organized by Han, Numadate, Goya et al. (2018). Also, the content validity of the Scale C3 has been verified, and a questionnaire to self-assessment for high school students version has been developed. In this study, a questionnaire to assessment from others for high school students and two questionnaires to assessment from self- and others for adults were developed. In addition, this study aimed to verify the reliability and construct validity of the Scale C3. Data were collected from high school students and adult subjects, of which self-assessment and others-assessment data were nearly equal. The reliability of the Scale C3 was high in all domains of Scale C3 (α=.707～.966). Also, the reliability of the whole Scale C3 was very high(α＝.976). As a result of validation for construct validity using structural equation modeling, a model showing a good fit was presented (χ2=463.924, df =78, TLI=.916, CFI=.945, RMSEA=.090, AIC=611.092). In this study, reliability and construct validity of Scale C3 were verified, and scale development was completed. It is expected that Scale C3 will be used as an objective assessment scale for continuous career development from the school education stage to adults.
