This study sought to determine the procedural influence on internal and external assessment scores of undergraduate research projects in vocational and technical education programmes in the university under study. A survey research design was used for the conduct of this study. The population consisted of 130 lecturers and 1,847 students in the selected Universities between 1995/1996 and 2005/2006 sessions. The study was analyzed using Statistical Package for Social Science (SPSS) version 13.0. The statistical tool used for the analyses were mean, standard deviation and multiple correlation. Cranach Alpha was used via SPSS to compute the internal consistency reliability of the instrument which was 0.86. The results showed that different criteria were applied not only at different universities but change with time. A number of suggestions were proffered to reduce the negative influence using procedure can have on internal and external assessment scores of vocational and technical education projects and enhance its reliability and validity.
