AGE
Children and adolescents aged 5–20
PROCEDURE
Inidividual administration. The standard procedure involves modular examination (to examine selected areas of individual functioning). The average examination time: intelligence (14 tests) – about 90 minutes; executive functions (4 tests) – about 30 minutes; competences: psychomotoric skills (3 tests) – about 20 minutes; socio-emotional competences (3 tests) – about 15 minutes; school competences (4 tests) – 30-60 minutes depending on the subject's age; work attitude (2 tests) – about 7 minutes
TEST USERS
Psychologists
The IDS-2 is a tool designed for a thorough evaluation of skills and competences in persons aged 5–20. The battery includes 30 tests to examine cognitive skills and competences. Since the IDS-2 consists 30 tests it can be applied for many different purposes including: assessment of intellectually disabled persons, assessment of persons with poor school performance, assessment of readiness for school, identification of children suspect of various disorders, and assessment of persons with outstanding skills.
Please note: All of our tests are published in Polish. There are not available other language versions of our tools. Contact us to buy this product.
The IDS-2 is a tool designed for a thorough evaluation of skills and competences in persons aged 5–20. The battery includes 30 tests to examine cognitive skills (intelligence, executive functions) and competences (psychomotoric, socio-emotional and school competences as well as work attitude). In addition the examiner can rate the subject's behaviour during examination. The focus is on dynamics of strong and weak points specific for a given development period. In practice the scales will usually be used in a modular way.
The IDS-2 is an enhanced continuation of the IDS Scales. It refers to a broad age range of 15 years (ages 5 to 20) and thanks to this allows for a comprehensive examination of all areas of development in children and adolescents. The IDS-2 becomes the most universal tool for the examination of these two groups available now on the market. Its modular structure, the variety of indices and possibilities of analysis offered allow for an easy adjustment of the examination scope to the examiner's needs.
It is common practice to select from a whole battery those tests that are used to study social-emotional competences. At the request of users, in addition to the standard IDS-2 sheets, we have prepared a separate sheet for the study of social-emotional competences.

*A shortened sheet allowing the calculation of screening and general IQ. We developed it at the request of our customers who want to calculate the general IQ based on the scores of the first 7 (1–7) intelligence tests, each of which relates to one ability from the Cattell-Horn-Carroll model. The results of validation studies have proven that it is equally reliable and valid as a measure of intelligence as the full IQ (i.e., calculated based on the results of 14 tests).
** At the request of our customers, who sometimes use the IDS-2 to study social-emotional competences, we have launched a new type of sheet to study only this area. These sheets are not included in the kit.
Since the IDS-2 consists 30 tests it can be applied for many different purposes including:
- assessment of intellectually disabled persons which includes differentiation of the normal and disability, defining disability levels (low vs. moderate) as well as the evaluation of the subject's strong and weak points,
- assessment of persons with poor school performance wtth a purpose of determining causes of the poor perfomance and developing therapeutic interventions,
- assessment of readiness for school according to the procedure described earlier for the IDS Intelligence and Development Scales for Children Aged 5-10, with some additional indices,
- identification of children suspect of various disorders (incl. dyslexia, ADHD, autism),
- assessment of persons with outstanding skills.
Reliability
Very high internal consistencies and stabilities for the IQs and factor scores as well as typically high (> .70) reliabilities of intelligence tests. High reliability of the general executive functions index as well as satisfactory (about .80) reliability of tests scores. In competences tests the general indices reliability is typically high (between .80 and .90) and fully justifies their being used in individual assessment. The general socio-emotional competences index os of a slightly lower reliability (about .70). Particual test scores usually have fully satisfactory reliability levels. Test scores for work attitude are characterized by the high internal consistency and stability.
Validity
Intelligence tests – intelligence structure as measured by the IDS-2 is parallel to the original version. Raw test scores increase with age. IQs and factor scores are signicantly correlated with parallel scores on the WAIS-R(PL). There is also siginificant correlation between the IDS-2 scores in primary and middle schools students and their school grades. Intellectually disabled children have low scores on the IDS-2. The battery allows for valid differentiation of intellectual disability levels (low vs. moderate).
Executive functions tests – their scores increase with age. They also show relationships with intelligence, esp. with the scores of the tests measuring information processing and resistance to distractors. They correlate with Children's Colour Trails Test CCTT. They are low in children with dyslexia and ADHD.
Competences tests – the validity of competences measurement was confirmed by the collected data. The confirmation of the socio-emotional competences tests proved the weakest, whereas that of the school competences tests proved the strongest. The results were significantly correlated with teacher's ratings concerning all different kinds of competences.
Norms
Norms were developed for 36 different age groups. For children aged 5–9 the quarter norms were developed, for those aged 10–14 – the semi-annual norms and for persons aged 15–20 – the annual norms. Calculated scores in the tests are defined on a scale of 19 points with an average of 10 and SD of 3. The IQs and factor scores are defined with an average of 100 and SD = 15. The IQs' ranges are between 30 and 170. For children aged 5–14 age equivalents were developed showing their respective ages in which a particular raw score in the test equals an average calculated score (10 points).
