Abstract
This study quantitatively provided evidence of content validity of BECE items in BST by estimating content validity index (CVI). Descriptive survey research designs were employed. Purposive and accidental sampling techniques were adopted in selecting 31 BST teachers in Abia State junior secondary schools. Three research questions were addressed. The instrument for data collection was 2021 BECE items in BST comprising four subtests with 30 items each. Item level CVIs, test level CVI and modified kappa statistic were computed. Findings revealed that 95% of the items of BST reported I-CVIs ranging from 0.70 – 1.00 and were accepted as having adequate content validity whereas the remaining 5% of the items, four from PHE and one from Computer Studies had low I-CVIs. The T-CVI yielded a high index of 0.95. Finally, kappa statistic adjusting for chance agreement indicated 0.763 – 1.00 for 95% of the BST items which proved excellent agreement among the experts.
