In this study, a method for preparing proficiency testing materials (PTMs) regarding soil-based metals is introduced; PTMs for a total of 6 metals, i.e., Cd, Cu, Pb, Zn, As, and Ni, were prepared. The level of concentration for each manufactured sample was measured according to Standard Methods. Soil quality, homogeneity, and stability were also evaluated. In order to verify the homogeneity of the manufactured soil PTMs, the standard deviation of proficiency and homogeneity of the samples were compared in accordance with the procedure stipulated in ISO 13528 and all samples were found to have good homogeneity. Furthermore, the stability of the PTMs was assessed as per the regulations specified in the ISO guide 35, and the results showed that the condition for stability was satisfied for the testing materials. The PTMs were distributed among soil environmental testing laboratories for proficiency tests and variations of z-scores from the test results were compared for different assigned values. Analytical results from inter-laboratory comparisons showed that the robust means were lower than the certified value for most of the target metals.
