Abstract	This article describes SIMREL, a software program designed for the simulation of alpha coefficients and the estimation of its confidence intervals. SIMREL runs on two alternatives. In the first one, if SIMREL is run for a single data file, it performs descriptive statistics, principal components analysis, and variance analysis of the item scores in the data file. The second alternative in SIMREL utilizes Monte Carlo simulation. It uses the data employed in the first alternative as population data and obtains estimators of each parameter using samples at the desired sample size and replication number from the population data.
