PROBLEM TO BE SOLVED: To provide a mechanism for selecting a probability model to efficiently and accurately estimate a user's comprehension degree probability in a user-adaptive test program.SOLUTION: In a user-adaptive test program, nodes are defined in which problems and solutions are associated with each other and which include comprehension degree probabilities, and a plurality of nodes are classified into a plurality of models (groups) according to different criteria. The user-adaptive test program includes: learning model storage means which stores for each model beforehand a directed graph having nodes interconnected with an arc; next candidate model selection means which selects for each model a next candidate model on the basis of an average comprehension degree probability obtained by averaging comprehension degree probabilities; problem proposition means which proposes a not-yet-posed problem in the next candidate model; solution determination means which determines whether a solution to a prepared problem is right or wrong; and comprehension degree probability update means which recalculates, for each user and for each model, comprehension degree probabilities in all other nodes in which the association with the not-yet-posed problem is made on the basis of an already-posed problem and whether the solution to the problem is right or wrong.SELECTED DRAWING: Figure 1
