Computer administering of a psychological investigation is the computer
representation of the entire procedure of psychological assessments - test
construction, test implementation, results evaluation, storage and maintenance
of the developed database, its statistical processing, analysis and
interpretation. A mathematical description of psychological assessment with the
aid of personality tests is discussed in this article. The set theory and the
relational algebra are used in this description. A relational model of data,
needed to design a computer system for automation of certain psychological
assessments is given. Some finite sets and relation on them, which are
necessary for creating a personality psychological test, are described. The
described model could be used to develop real software for computer
administering of any psychological test and there is full automation of the
whole process: test construction, test implementation, result evaluation,
storage of the developed database, statistical implementation, analysis and
interpretation. A software project for computer administering personality
psychological tests is suggested
