SCALIQ Psychometrics
SCALIQ is a psychometric research and development institute. Our main research focus is giftedness and education.
The first step in the path to better research about giftedness and to more suitable education for gifted learners is early and proper identification of gifted children. To that end we develop psychometric instruments: IQ-tests and other psychometric tools designed for people with an above average IQ. Tests which allow a gifted person to really shine. That measure intelligence, not circumstances. That take into account challenges that follow from AD(H)D, ASS, dyslexia or fear of failure. And: that are fun to take!
Examples of products we developed are:
- The KIQT+: the first intelligence test specially designed for children from 5 to 10 years of age with an above average intelligence, in which Item Response Theory is used to calculate scores based not only on how many, but also on which specific questions are answered correctly.
- The ZOOV+ and VOQS: online, fully adaptive, group administered screeners to help identify intellectually gifted students in primary (ZOOV+) and secondary (VOQS) education.
- The SCALIQ Adaptive Intelligence Screener (SCAIS): a quick and easy 1-on-1 screener for possible high (or low) intelligence in children and adolescents ages 5 tot 25, making it easier for psychologists to decide which further tests and assessments might be appropriate.
- The ORP+: a tool for educators and gifted specialists, with which it is possible to visualise the cognitive development of gifted children compared to that of their classmates. It can help with decisions about gifted interventions like pull-out programs and/or (radical) accelleration.
Our main goal in everything we do is to help gifted learners thrive.
"An IQ test or a portion of such a test is only useful for the assessment of giftedness
to the extent that it measures g."
- Linda Kreger Silverman
The KIQT+
developed especially for testing
5 to 10 year old (highly) gifted children
The KIQT+, or Kinder IQ Test + (Children's IQ Test Plus), is made for presumebly (highly) gifted children 5 to 10 years old (up to the day before their 11th Birthday). The range of this test is an IQ of 105-170 and it's highest reliability lies well within the highly gifted range, while other tests' highest reliabilities lie mostly within the average range (IQ 85-115).
And, not unimportantly: the KIQT+ is a lot of fun to take!
What makes the KIQT+ different from other intelligence tests:
- Reliable measure of intelligence (g) up to an IQ of 170.
- A good fit for children from all cultural backgrounds, including non-native speakers.
- Well suited for children with AD(H)D, ASS, hearing difficulties, colorblindness, dyslexia and dyscalculia, or children who deal with fear of failure, perfectionism or difficulties with time pressured assignments.
- Takes into account that gifted children are prone to more complex thinking.
- Less emphasis on abilities that are dependant on upbringing and cultural background, like vocabulary or common knowledge.
Would you like to know more about the development and (scientific) background of the KIQT+? Please read our whitepaper. It is written in such a way that a scientific and/or testing background is not necessary to read and understand it.
The norming process of the KIQT+ was completed in 2021. It has been reviewed by the Dutch Committee on Tests en Testing (COTAN), as a result of which we now know for sure that we have developed a high-quality, reliable and appropriate test. The KIQT+ is for sale via this website (currently only within the Netherlands and Belgium, but we are looking into expanding the norms for use in other European countries).
The KIQT+ is being used by over 130 psychologists and other diagnosticians working with gifted children. Are you looking for a psychologist for intelligence testing with the KIQT+? Check out this map that shows practices working with the KIQT+.

Because you wouldn't measure a giraffe with a standard ruler either


The ZOOV+
a fully adaptive group administered screener to help
identify gifted learners in education
Identifying gifted children can be a challenge. Gifted learners don’t always share the same characteristics, and not all of them do as well in school as should be expected. Our adaptive group administered screener helps educators find gifted students (ages 5 tot 20) in primary and secondary education, making it a starting point to offering them the education they need to fully develop their potential.
The ZOOV+ does not rely on language or acquired knowledge, which means it is suitable for children of all backgrounds (including non-native speakers) and educational levels.
Group administration makes it possible to screen large amounts of students in a short timespan, and being adaptive means all students can participate. Some gifted learners are experts at hiding their talents from teachers, but the fun visual puzzles in this screener will be sure to draw them out!
The SCAIS
a quick adaptive 1-on-1 screener for possible high (or low) intelligence in children and adolescents
The SCALIQ Adaptive Intelligence Screener (SCAIS) is a quick and easy to administer test to screen for possible high or low intelligence in children and adolescents (ages 5 tot 25). It can help psychologists and diagnosticians decide which further tests and assessments might be appropriate.
The SCAIS is adaptive and does not rely on language or aquired knowledge, which means it is also suitable for use with non-verbal children and non-native speakers.
