Publishing September 2021, the IDS-2 is a global cognitive assessment of the 'whole child', unparalleled in its ability to identify their knowledge, strengths, and developmental needs in one complete picture.

Ages 5 years to 20 years and 11 months.
In addition to English, the IDS-2 is available or currently being adapted in Danish, Dutch, Finnish, French, German, Italian, Norwegian, Polish, Portuguese (Brazilian), Spanish and Swedish.
The second edition of the highly successful German IDS, first published in 2009, the IDS-2 provides in-depth information on the child’s strengths and developmental needs, enabling testers to identify with precision where support is needed to help them achieve their full potential.
The IDS-2 offers the most comprehensive diagnostic assessment available, with 30 subtests covering the six domains: two cognitive domains (Intelligence and Executive Functions) and four developmental domains (Psychomotor skills, Social-emotional skills, Scholastic skills, and Motivation and Attitude).
Developed in a unique modular framework with child-friendly test materials, the IDS-2’s flexible design makes it easy to personalize the testing session. Booklets and record sheets are colour-coded for ease of use and scoring is conducted online for convenience and accuracy.
The IDS-2 can be used across a variety of diverse applications, including identifying and diagnosing intellectual disabilities and learning disorders, evaluating cognitive and motor skills, understanding emotional strengths and weaknesses.
The IDS-2 is valuable in the education sector to determine aptitude, assist with school enrolment or transition between primary and secondary, providing meaningful results to pinpoint specific actions and interventions.

Scoring and reporting
Scoring is done online through the Hogrefe Testsystem (HTS), eliminating errors and removing the need for manual scoring. No licence is necessary; a scoring credit is included with the purchase of each paper record form. Seven separate report options are available through HTS – including Intelligence, IQ-Screening, Executive Functions, General Development (for the 3 different age groups) and a General Profile.
How does the IDS-2 compare to the WISC-V?
With the IDS-2, users will benefit from:
The IDS-2 is designed for use by a psychologist or professional who has had training and/or experience in administering cognitive or developmental assessments to children and adolescents. Users in the UK would be qualified with an HCPC registration as a Practitioner Psychologist and/or be a Chartered Psychologist with the BPS. Child Psychologists and those with the protected title of Educational Psychologist, Clinical Psychologist, Forensic Psychologist, or Counselling Psychologist are also typically considered qualified to administer the IDS-2.
All IDS-2 users are encouraged to work with the Hogrefe team as we encourage e-learning and other learning opportunities, where examples of the administration process and item types are reviewed and discussed. Contact firstname.lastname@example.org to learn more.
The reliability of the IDS-2 was established by measuring internal consistency using Cronbach’s alpha and with additional test-retest studies during the development of the UK edition.
With respect to validity, several studies in German, Dutch and Italian were completed that showed very good correlations to other cognitive assessments (e.g. the WISC-V) and in the UK, we also found that to be true. As the IDS-2 also measures other areas that provide a fuller picture of the individual’s strengths and areas for development, good correlations were also found with assessments designed to measure those constructs (e.g. the BRIEF-2 for Executive Functions; the MABC-2 for Psychomotor Development; etc.).
The IDS-2 has been standardised on 1,367 children and adolescents aged 5;0 to 20;11 years in the UK. Standardisation testing was conducted by Oxford Brookes University in 2018–2020. There are norms for each year age group between 5;0 and 20;11. School half-year norms are also available – allowing highly accurate interpretations to be made.
The IDS-2 has a modular design so that each assessment session covers the areas needed in an individual way. Testing times (approximate) are:
