Abstract：This paper compares the full-scale verification method with the decimeter verification method, which are used for the verification of levelling staff. By using a paired-samples t test, we compare the results obtained by the two verification methods, and evaluate the repeatability and reproducibility of the results. The results obtained by the two verification methods show no significant differences| the reproducibility error occurred in both verification methods and the difference which occurred in the comparisons obtained by the two verification methods are of the same order of magnitude.
