Description: The APIS-Z(R) Test Battery is a multidimensional tool designed to assess general intelligence. Such a definition of what is measured refers to the hierarchical theories of intelligence (Vernon, 1965; Carroll, 1993). According to this conception a general and hidden intellectual skill exists on which other, more precise types of skills are based. Another important theoretical assumption of the present test is that measurement refers to the level of crystallized intelligence (Cattel, 1971) which is defined as a skill conditioned by individual experience and used for specific problem solving. Despite the fact that the administration time of various tests from the APIS-Z (R) battery is limited it is assumed that they are rather “power” and not “speed” tests.

The APIS-Z (R) is a revised version of the APIS-Z battery. It consists of eight tests: Behaviours, Squares, Synonyms, Classification, Number Transformations, New Words, Blocks, Stories. Theoretical structure of the APIS-Z involves four types of skills: abstract-logical, verbal, visual-spatial and social. Each of these skills is represented by two tests. Compared with the first edition of the APIS-Z the new version includes a number of revisions the purpose of which was to eliminate certain weaknesses of the tool. On that occasion a new study was conducted to prove validity of the tool in the context of career counselling and selection processes. Updated norms were also developed for the adult population and for the population of last grades of high school students. 

Reliability: High internal consistency of the general score, moderately high consistencies for the  component tests. High stability for adults and moderately high for high school students.

Validity: Moderately strong correlation of the APIS-Z(R) general score with scores in the TMZ and Raven's tests; slightly less strong correlation in the case of the component test scores. Weak or moderately strong correlations of the APIS-Z(R) scores with creativity tests scores (TCT-DP and TPE).

In the student sample the APIS-Z(R) scores are positively correlated with school grades, although the correlation is not very high. The scores, however, allow to predict learning difficulties (average grade < 3,0 [C]). In the adult sample score profiles in the component tests are different for groups with different education levels and types of work. The scores also differentiate persons with high school education only from those having college or university diploma.

In the process of the test revision comparability of the traditional paper-and-pencil version and the electronic version was also assessed. The results prove internal consistency of the electronic version to be as high as in the traditional version. No significant differences between mean scores in the two versions were found out. 

Norms: For adults aged 20-67 with both high school and university education (general norms as well as specific norms for each of the five age levels). For last grades of high school students.

Applicability: Selection, recruitment and career counselling. The APIS-Z(R) can be applied in career counselling for adolescents esp. when choosing the right type of education is concerned (it includes important and valuable norms for last grades of high school students). It can be applied in recruitment processes, employees selection and career counselling for adults. It includes norms which refer to the population of productive age persons with high school and university education who are the majority of those applying for jobs in recruitment processes or of the unemployed actively seeking new jobs.
