Analysis

The Vocational Self-Efficacy Test (TEPA) is based on Holland’s career development model. It consists of 57 statements describing various professional activities and aims to assess an individual’s vocational self-efficacy.

Purpose

The purpose of the test is to evaluate a person’s ability to recognize and complete occupational tasks.
Occupations are categorized into six groups:
Realistic
Investigative
Artistic
Social
Enterprising
Conventional

Scoring

Scoring in TEPA is done at two levels:
a) Evaluation of the subscales
b) Overall evaluation
The total score is the sum of the individual subscale scores. The three subscales with the highest scores generate a three-letter code, which corresponds to specific occupations.

Statistical Analysis

The test was conducted on a sample of 1,782 9th-grade students.
Scores are presented in both percentile ranks and T-scores.
The mean total scores for each subscale were:
Realistic occupations: 20.25 (SD = 8.45)
Investigative occupations: 19.23 (SD = 6.82)
Artistic occupations: 25.94 (SD = 7.74)
Social occupations: 18.60 (SD = 5.61)
Enterprising occupations: 25.18 (SD = 7.93)
Standard scores differ between male and female students.

Validity and Reliability

Confirmatory factor analysis was used to validate the structure of the test.
The results showed that the theoretical model is supported by the data.
Correlation indices ranged from 0.29 to 0.54 (p < 0.001).
Cronbach’s alpha ranged from 0.83 to 0.93, indicating high internal consistency.
