Staff Development and Digital Leadership as Predictors of Educational Outcomes in Public Secondary Schools in Calabar Education Zone, Cross River State, Nigeria

The calibre of secondary school graduates is substantially shaped by the professional quality of their teachers and the technological infrastructure that supports teaching and learning. This study investigated the extent to which staff development and digital leadership predict educational outcomes (cognitive, affective, and practical) in public secondary schools in Calabar Education Zone of Cross River State, Nigeria. Two null hypotheses were formulated and tested at the .05 level of significance using a correlational research design. The study population comprised all 94 public secondary schools in the zone; 64 schools were selected through stratified random sampling. Data were collected using two validated instruments: the School Development Variables Questionnaire (SDVQ) completed by teachers and the Educational Outcomes Questionnaire (EOQ) completed by SS2 students. Cronbach alpha reliability coefficients ranged from .77 to .91 across all subscales. Simple linear regression was used to test each null hypothesis, and hierarchical multiple regression determined incremental contributions within the full six-variable model. Results showed that staff development significantly predicted overall educational outcomes (R² = .342, F1,62 = 32.219, p < .05), as well as cognitive outcomes (R² = .167), affective outcomes (R² = .250), and practical outcomes (R² = .281). Digital leadership was an even stronger predictor, accounting for 38.2% of the variance in overall educational outcomes (R² = .382, F1,62 = 38.310, p < .05) and significantly predicting all three outcome dimensions. It was concluded that both variables are complementary and meaningful contributors to educational quality in public secondary schools. The study recommends sustained, targeted staff development programmes and substantial government investment in ICT infrastructure and digital leadership capacity in Calabar Education Zone.
