Children aged 6-10 (DMI-2M) and 9-13 (DMI-2S).
Individual or group administration (depending on the version), split into two sessions; no time limit; in the version for individual testing children must justify their answers.
Especially useful for:
Psychologists (MA in psychology required); educators – after completing the training
B2 – for psychologists; other professionals only after general psychometric training and test training

The DMI-2M and DMI-2S are far-reaching modifications of the earlier DMI. They are used to assess children’s intellectual potential on the basis of the efficiency of concrete operations. The versions meant to be administered individually are an attempt to combine psychometric assessment with the ideas underlying dynamic assessment so as to assess the developmental advancement of operational thinking and to detect its deficits.

DESCRIPTION: Each test consists of 76 problems based on verbal, drawing and numerical  material, collected in two booklets. The child is required to complete classes, series and analogues by selecting the necessary element from a set of five every time and (in the individual versions) to justify its choice. The child’s answers are rated on  a rating scale from 0 to 3 depending on how correct they are. Qualitative analysis of types of errors and (in the individual versions) types of justifications is also possible.

RELIABILITY: High internal consistency.

VALIDITY: Established construct and concurrent validity (developmental changes, correlations with school grades, correlations with the Raven Progressive Matrices).
NORMS: Standard ten norms for representative national Polish samples, developed separately for individual and group administration: DMI-2M – for age levels 8, 9 and 10 (group administration) and 6, 7, 8, 9, and 10 (individual administration); DMI-2S – for age levels 9, 10, 11, and 13 (group administration) and 11 and 13 (individual administration).

APPLICATIONS: DMI-2 may be used instead of, or in addition to, intelligence tests to assess general mental level in children and also to assess the level of development of concrete operations as an important premise for predicting school achievement or detecting the reasons for scholastic difficulties. The qualitative information gleaned from this test (particularly when administered individually) may be helpful in the planning of corrective-educational interventions.
