Scientific Research and Collaboration

Join us in our data collection efforts

Psychological or Educational Professional? Hogrefe Publishing is looking for psychological and educational professionals to join our team of experienced examiners who collect standardization data for our clinical and educational assessments. Examiners recruit and test qualified participants and submit the data to Hogrefe Publishing for inclusion in our pilot studies, norming sample or validity studies. Examiners work with internal staff to become fluent in administration of the tests, to understand who a qualified candidate to test, and to learn the processes and procedures for collecting and submitting data.


Part of a University Program? Hogrefe Publishing wishes to collaborate with university programs so students can practice their assessment skills and have access to data to use for creating publications and presentations. Programs will be responsible for identifying and testing children as well as securing all associated parental permissions. Grant money is awarded to participating programs and can be used at the discretion of the university. The university may keep the test kits used for the study.


Part of an organization looking for a unique fundraising idea? Hogrefe Publishing would like to partner with your organization to recruit and test examinees as part of our assessment research studies. Schools, sports clubs, places of worship, and other organizations may participate as an official research site. As a research site, programs will distribute research flyers and recruit study participants from its membership. Organizations will receive $20.00 per participant recruited and tested. Compensation can be in the form of a check, Amazon gift card, or donations of specific items.

Early Sociocognitive Battery (ESB)

The ESB is a new assessment for preschool children that is predictive of later language and social communication difficulties including autism spectrum disorder (ASD). Typical users are speech and language therapists as well as clinical and school psychologists.

As a primarily non-verbal assessment tool, the ESB is standardized in the U.K. with children aged 2–5 years from diverse language backgrounds. It is a battery of three subtests assessing sociocognitive skills known to be associated with language development and impaired in children with social communication difficulties and ASD. The subtests measure social responsiveness, joint attention and symbolic comprehension to identify deficits in key sociocognitive skills and help early years professionals target their intervention strategies appropriately. The ESB contains a variety of toys and objects designed to engage young children, and the assessment is quick, taking 15 minutes or less to complete.

Intelligence and Development Scales – 2nd Edition (IDS-2)

The IDS-2 is a global cognitive assessment of children designed to identify their knowledge, strengths and relevant areas for development. With 30 subtests covering six domains, the IDS-2 offers a modular framework with user-friendly test materials and makes it easy for the practitioner to personalize the testing session for each child and adolescent from 5.0–20.11 years.

The IDS-2 is now available in U.K. English and is already published in German, Dutch, Polish and Italian. It is in progress in Danish, Finnish, French, Norwegian, Brazilian Portuguese, Spanish and Swedish.

Data will be collected using a digital record form that includes a timing device, automatic application of basal and ceiling rules, and real-time calculation of raw scores. Included are a small set of manipulatives and response booklets for performance subtests.

Snijders-Oomen Nonverbal – Digital (SON-Digital)

The SON-Digital is a fully digital assessment administered via one tablet to individuals ages 4–21+ years. The six subtests are from the well-known Snijders-Oomen Nonverbal Intelligence Test (SON-R) used in the Netherlands and German-speaking countries for the last 40 years. The assessment requires no verbal or written instructions, making it ideal for children and adults with language disorders, hearing loss, or other characteristics that may impact performance on traditional cognitive assessments.

The subtests, which measure fluid reasoning and visual-spatial skills, combine to provide an overall estimate of cognitive ability. With the new digital format, subtest directions and practice items are automated. Examiners will guide the assessment by ensuring that instructions are understood and deciding if the test taker is ready to proceed to the next subtest. All examinee responses will be nonverbal and captured by touching the screen. Raw scores will be automatically calculated and, to reduce frustration and administration time, age-based starting points and discontinue rules will be automatically applied.
