Purpose of the Questionnaire

The aim of the questionnaire was to develop and standardize a brief tool for measuring overall job satisfaction. While valid questionnaires already exist in Greece for assessing job satisfaction by individual factors, measuring satisfaction only by factor is like trying to judge a painting by looking at its colors separately—it doesn’t always capture the whole picture. This new tool seeks to understand the overall feeling educators have about their work.

Questionnaire Analysis

The Teacher’s Satisfaction Inventory (TSI) was developed by Golia in 2014 and consists of 20 questions designed to assess satisfaction among public primary and secondary school teachers. Originally developed in 2012, it was created to fill the gaps left by existing tools—like building a bridge where others had only laid stepping stones.

Scoring

The TSI-20 is divided into five dimensions:
Principal
Colleagues
Students
Working conditions
Nature of the job
Responses are recorded on a 5-point Likert scale (1 = Strongly Agree, 5 = Strongly Disagree). The questionnaire was originally developed in Greek, is standardized, and reflects the modern socio-economic context of the country—much like an updated GPS that navigates current educational landscapes rather than outdated routes.

Statistical Analysis

High average scores show that teachers generally have no complaints about their work—except for their salary. So, like a garden that thrives despite dry soil, their professional satisfaction grows even under financial constraints. However, the high standard deviation values indicate varied responses, showing that not all teachers see the garden the same way—some enjoy the flowers, others notice the weeds.

Validity and Reliability

The reliability coefficient for the scale is quite high, with Cronbach’s alpha = 0.889. This means the tool is trustworthy, like a well-tuned instrument in an orchestra—it plays in harmony without needing to remove any “off-key” questions. The reliability scores for the individual dimensions also reached high levels, with alpha values ranging from 0.746 to 0.923, reinforcing that the questionnaire performs well across its various components.
