Traditionally, technical drawing teachers are supposed to use drawing board, instruments and drawing sheet to prepare marking schemes to help them score students work appropriately but due to time constraints this duty has become a challenge to them to perform in schools these days. The study was about the accuracy of AutoCAD generated marking schemes over the traditional way of using annotated sketches to help assess students' technical drawing scripts and the perceptions technical drawing teachers have in the use of AutoCAD application programs in their test administration in schools. The target population for this study was all the 57 technical drawing teachers in the Cape Coast Metropolis according to the Metropolitan Education Office. Out of this number 50 of the teachers agreed to participate in this study. All the participants were second cycle teachers in the Cape Coast Metropolis in Central Region of Ghana. In the study, self-completion questionnaire and a study of students' marked examination scripts were methods used in data collection. The study used quantitative research methods with aspects in experimental and descriptive survey.
