In the middle of the last century due to the development of the theory of latent variables it is become possible to measure latent variables on a linear scale. It gives the opportunity to conduct in social systems more advanced research. Measuring tool in these researches is the test based on Rasch model. It is considered that test as a measuring tool is a set of items with uniformly increasing difficulty. In the paper in the framework of simulation experiment there is presented the technique of estimation of influencing of test items distribution on the standard error of measurement of latent variable.
