The researcher administered questionnaires and in-depth interviews to teachers and principals respectively. Validity of research instruments was based on content validity through expert judgement. Reliability of research instruments was ensured by deriving and adapting items developed by other researchers.

The researcher used descriptive statistics to analyse questionnaire items on Likert scale. The researcher employed Chi-square, Pearson product moment correlation, Multiple linear regression and Analysis of Variance to test the research hypothesis at 95% confidence interval. Thematic analysis technique was used to analyse qualitative data and presentation of finding in thematic narratives. The study revealed career development has statistically significant influence on teacher turnover intentions; avenues to advance career (β = 0.009, p = 0.921 > 0.05), career growth programmes (β = - 0.020, p = 0.832 > 0.05), scheme of service (β = - 0.032, p = 0.770 > 0.05), career growth policies (β = 0.030, p = 0.693 > 0.05) commitment to TSC (β = - 0.145, p = 0.594 > 0.05) and funds for career advancement (β = 0.151, p = 0.158 > 0.05).
