This study investigated the effects of professional development and resource management on
teachers’ effectiveness in public secondary schools in Wukari Local Government Area. The
study adopted a descriptive survey design. The population comprised 470 teachers from 25
public secondary schools, while a sample of 216 teachers was selected using Taro Yamane’s
sampling formula and multistage sampling techniques. Data were collected using a structured
questionnaire titled Teachers’ Effectiveness and Institutional Support Questionnaire (TEISQ).
The instrument was validated by experts in educational management and measurement and
evaluation, while reliability coefficients ranging from 0.82 to 0.89 were obtained using
Cronbach’s alpha. Data were analyzed using mean, standard deviation, regression, and
ANOVA statistics at a 0.05 level of significance. Findings revealed that professional
development significantly influenced teachers’ effectiveness, as teachers who participated in
workshops, seminars, and training programmes demonstrated improved instructional
delivery, classroom management, and teaching competence. The study also found that
resource management significantly affected teachers’ effectiveness. Although some
instructional materials were available, inadequate maintenance of facilities and poor
distribution of resources negatively affected effective teaching and learning. The study
concluded that professional development and effective resource management are critical
determinants of teachers’ effectiveness in public secondary schools. It was recommended that
educational authorities should strengthen continuous professional development programmes
and improve the provision, maintenance, and equitable distribution of educational resources
to enhance teachers’ performance and overall educational quality in public secondary
schools.
