ACT general intelligence

Assessment

What is it?

The ACT General Intelligence is an adaptive intelligence test designed to measure a candidate’s cognitive abilities across three domains: numerical reasoning, abstract reasoning, and verbal reasoning. The test adapts in real-time to the candidate's responses, adjusting the difficulty of each question based on whether the previous answer was correct or incorrect. This dynamic approach ensures a tailored and more accurate assessment of each candidate’s intelligence level.

Unlike traditional tests, the ACT General Intelligence minimizes the frustration of candidates being confronted with questions that are too difficult or too easy. With an item bank of over 200 questions per sub-test, the system selects questions suited to the individual’s level, allowing for a quicker and more precise determination of cognitive abilities.

Measurement Objectives

The ACT General Intelligence measures three key cognitive areas:

  • Numerical Reasoning: The ability to identify logical connections in number sequences and use that information for decision-making.
  • Abstract Reasoning: The capacity to recognize patterns and solve problems based on those patterns, a skill critical for roles requiring conceptual thinking.
  • Verbal Reasoning: The ability to analyze relationships between words and draw conclusions, essential for jobs that involve verbal and written communication.

These cognitive abilities are vital for roles where problem-solving, analytical thinking, and effective communication are key to success.

Use

The ACT General Intelligence test is useful for both selection and advisory processes, making it suitable for evaluating candidates across many industries. It’s especially helpful for roles that require strong cognitive skills, such as data analysts, managers, technical professionals, and consultants. Employers can tailor the test to a candidate’s educational level, whether MBO, VMBO, HBO/Bachelor, or WO/Master, allowing flexibility for different roles and positions. This test is commonly used for assessing both entry-level and senior roles, offering valuable insights into a candidate’s intellectual abilities and potential for success.

Results

ACT General Intelligence results include a general IQ score based on numerical, abstract, and verbal reasoning sub-tests, each with individual scores. The report shows an 80% confidence interval for score reliability and presents sten, percentile, and T-scores, allowing employers to compare candidates against MBO, HBO/Bachelor, and WO/Master reference groups. This comprehensive report supports data-driven hiring by offering a clear view of candidates' cognitive abilities for specific roles.

Development

The ACT General Intelligence test was developed with a research-backed approach to enhance the accuracy of cognitive assessments. Its adaptive design provides precise, efficient measurement of cognitive abilities. With the optional Approve Test, candidates complete the main test remotely, followed by a brief confirmation test in a controlled setting to verify results. Any discrepancies may lead to a retake under supervised conditions, ensuring fairness and reliability.

Reference Group

The ACT General Intelligence assessment is benchmarked against a diverse norm group to ensure accurate and reliable results. The reference group includes candidates across educational levels:

  • VMBO (N=300)
  • MBO (N=659)
  • HBO (N=570)
  • WO (N=490)

Reliability

The assessment has demonstrated high reliability across all educational levels:

  • VMBO: Subtests 0.88, G-score 0.96
  • MBO: Subtests 0.88, G-score 0.96
  • HBO: Subtests 0.86, G-score 0.96
  • WO: Subtests 0.85, G-score 0.95

These reliability scores confirm that the ACT General Intelligence assessment consistently provides dependable insights, tailored to each candidate's level of education.
