Background: Reaction time (RT) is the time interval between stimulus and response. RT can be measured by ruler drop method (RDM). Till date, there is no set standard reference norm available for the school children by RDM. Objective: To determine the standard reference norms for RT in school going children. Methods: A sample of 152 students will be recruited based on predetermined set of inclusion criteria from the recognized primary school by convenience sampling method for the cross-sectional study. RT of all the recruited students will be estimated by RDM. Statistical analysis: Normality of the collected raw will be established by Kolmogorv Smirnov test of normality. Descriptive statistics will be used to report the standard reference norms of RT in mean (standard deviation). Independent t-test or Mann Whitney U test will demonstrates the gender differences of RT by RDM among the primary school children. Conclusion: This study will act as the foundation for other studies using RDM for reporting RT.
