Abstract: Abstract This study examined the influence of regular calibration protocols on the accuracy and reliability of measuring instruments in technical education laboratories in Kwara State, Nigeria. Recognizing the importance of precise measurements in vocational training, the research assessed how scheduled calibration impacts measurement precision, consistency in assessments, and reliable research outcomes. This study used the 42 respondents due to manageable size of the population, with a descriptive survey design that utilized questionnaires to collect data from technical education lecturers, laboratory technologists, and Electrical/Electronic Technology students. Validity was established by two Lecturers from Electrical/Electronic Department and one from Measurement and Evaluation Department, University Nigeria Nsukka. and reliability via Cronbachs Alpha Coefficient value (0.70). Data were analyzed using mean and standard deviation. The null hypotheses were tested using ANOVA at a 0.05 significance level. Findings indicated strong agreement among respondents that regular calibration significantly enhances instrument accuracy (grand mean = 4.24; F (2,306) = 0.669, p = 0.000). It also significantly influences reliability and consistency during practical and assessments (grand mean = 4.25; F (2,306) = 1.169, p = 0.001). Furthermore, implementing these protocols significantly contributes to improved instructional delivery, student performance, and quality assurance (grand mean = 4.24; F (3,153) = 1.273, p = 0.000). All null hypotheses were rejected. The study concludes that regular calibration is not merely maintenance but a vital component for ensuring quality assurance, instructional effectiveness, and professional standards in technical education, thus being indispensable for high-quality training.
