Data were collected and analysed using Statistical Package for the Social Sciences (SPSS). The findings revealed a high validity and reliability in the questionnaire with the range 0.65 ≤Cronbach’s α≤0.95. The finding reported the reliability of the questionnaire using Cronbach's Alpha method. The finding showed high reliability in the questionnaire of psychological well-being questionnaire α=0.93, job satisfaction questionnaire α=0.91 and student-teachers relationship questionnaire α=0.89. In conclusion, these three variables are important as mentioned in the Malaysian Education Development Plan (PPPM) 2013-2025 to improve preschool quality and encourage universal enrolment by 2020.
