Findings also showed that head teachers and teachers did not significantly differ in their perception on records checking on teachers’ performance (P=0.09117,) whereby, majority of the head teachers 11 (73.0%) and teachers 144 (72.0%) of almost the same proportion strongly agree and agree that record checking by head teachers impact teachers performance while a minority of the head teachers 4 (27.0%) and teachers 56 (28.0%) disagree and strongly disagree.
