This study was undertaken to develop and validate an instrument for assessing student’s practical performance in electronic in Technical Colleges in Nigeria with focus on Delta State Technical Colleges. This is sequel to the fact that Electronic teachers/lecturers in these schools seem to improperly assess students’ practical job and also lack proper instrument for correct measurement of their practical performance. The study adopted an instrumentation research design. A total of 27 electronic teachers consisting of holders of B.Sc Technical Education in Electronic Technology, HND Electronic Technology plus PGDE and FTC Electronic Technology plus TTC constituted the population as well as sample of the study. Mean statistics were used to analyze research questions that guided the study while Harrow’s (1972) taxonomy of psychomotor objectives was used to determine the content validity of the instrument. Research question 4 wasanalyzed with the use of Cronbach Alpha. There were 2 null hypotheses analyzed with one-way analysis of variance (ANOVA) while Scheffe’s multiple range test was used to show the difference in direction among the three groups of raters. Theproduct of this study is the development of an instrument titled: “Electronic Work Test Instrument, EWTI”. This instrument was validated by experts in the field of electronic using identification of the psychomotor/ practical areas of NTC curriculum in electronic to build a table of specification based on Harrowstaxonomy of practical objectives. This followed a process of operational analysis and subsequent generation of items which closely fit the table of specification. The appropriateness of the test items was also strengthened by experts in Technical and Measurement and Evaluation in terms of face and content validity of the newly developed EWTI. Based on the comments of these experts, the newly developed instrument contains electronic tasks considered suitable to assess students’ electronic practical work in Technical Colleges. The consequence of the result of this study gave rise to appropriate recommendation that EWTI should be used by electronic teachers to assess students’ practical performance in electronic work in technical colleges while seminar/workshops should be organized from time to time for electronic work teachers by various State Post Primary Education Boards in other to get them familiarized with the methods of using this instrument, among others. The study gave a conclusion that the EWTI will be an effective assessment tool to determine students’ competence and make them to become capable hands that are required in today’s electronic workshops/ industries.
