Scale for Coordinate Contiguous Career (Scale C
3) was organized by Han, Numadate, Goya et al. (2018). Also, the content validity of the Scale C
3 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 C
3. 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 C
3 was high in all domains of Scale C
3 (α=.707~.966). Also, the reliability of the whole Scale C
3 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 (χ
2=463.924,
df =78, TLI=.916, CFI=.945, RMSEA=.090, AIC=611.092). In this study, reliability and construct validity of Scale C
3 were verified, and scale development was completed. It is expected that Scale C
3 will be used as an objective assessment scale for continuous career development from the school education stage to adults.
