Psychometric properties of the Teacher Achievement Striving Scale (TASS) and the
Teacher Occupational Commitment Scale (TOCS)
Teacher Achievement Striving Scale (TASS)
An exploratory factor analysis using maximum likelihood estimation was conducted on
the results from the TASS. One factor was extracted based upon examination of the
eigenvalues and the scree plot. This factor accounted for 28.83% of the variation, and
was labelled ‘teacher-specific achievement striving’. This is a low percentage of
variation for a single-factor solution, but with such a limited sample size further
validation work could not be conducted. All 10 items loaded on this factor with factor
loadings greater than .30. The items with their respective factor loadings are presented
in Table 1. Items 1, 2, and 7 were quite weak items with factor loadings below .40,
although the remaining items displayed quite good validity with factor loadings from .51
to .69
