Abstract: The main purpose of the study was to develop an instrument for assessing students' performance in lathe machining operations at technical college level.Two research questions were posed to guide the study. Instrumentation research design was adopted for the study and the instrument used for data collection was a structured questionnaire developed by the researcher. Three psychomotor objectives identified by the research, were transformed to items for the draft of Machining Process Skill Test Instrument (MAPTI). Draft of the MAPTI was face and content validated by three (3) experts. The data generated were analysed using mean, standard deviation, and Analysis of Variance (ANOVA). The Content Validity Index (CVI) and the reliability index (RI) were 0.70 and 0.83respectively. The results of the data analysed relating to psychomotor objectives for assessment revealed 50 operations along 3 tasks were consider appropriate for the draft MAPTI. it was recommend that among others Teachers of mechanical engineering craft trade should use the instrument (MAPTI) in measuring the strength and weaknesses of their students in practical lessons and also during teacher made test and that teachers should use the MAPTI using applicable operations as per level covered content area, and adjust grading to suit purpose.
