The CAT4 scoring system consists of several key components. Decoding these CAT4 scoring components involves understanding how a student’s performance on the CAT4 test is evaluated and measured. Interpreting your child’s CAT4 scores involves considering these various metrics together. It’s essential to discuss the results with your child’s school and educators to gain a comprehensive understanding of their cognitive abilities and identify areas where they excel or may need additional support. These scores can be valuable in tailoring educational strategies to meet your child’s specific needs and potential.

Explaining scores per CAT4 skills section

  1. Inference Ability Score: This score reflects your child’s ability to draw conclusions or inferences from the information provided. It measures their logical thinking skills.
  2. Working Memory Score: This score assesses your child’s ability to hold and manipulate information in their mind, which is crucial for tasks that require mental calculation and problem-solving.
  3. Verbal Reasoning Score: This score evaluates your child’s ability to work with language and verbal information, including vocabulary, understanding of relationships between words, and comprehension.
  4. Non-Verbal Reasoning Score: This score measures your child’s ability to work with visual information, patterns, and relationships between shapes and figures.
  5. Quantitative Reasoning Score: This score assesses your child’s mathematical reasoning skills, focusing on their ability to solve numerical problems and understand quantitative information.
  6. Spatial Ability Score: This score evaluates your child’s spatial awareness and their ability to work with visual information to identify patterns and relationships.

Explaining the stats on the CAT4 report for parents

GL Education’s CAT4 report for parents uses several statistical terms you’ve probably not seen before. The following explanations are provided by specialist psychometrician Rob Williams:
  1. Raw Score: This is the simplest aspect of scoring. It represents the number of questions a student answers correctly on the CAT4 test. Essentially, it’s a count of how many points you earn based on correct answers.
  2. Standard Age Score (SAS): The SAS is a critical metric that allows for a fair comparison of a student’s performance relative to their age group. It’s a bit like assigning your performance a “grade” that’s adjusted for your age. The average SAS is set at 100 for each age group, and there is a standard deviation of two. So, if your SAS is above 100, it means you performed better than most students your age, and if it’s below 100, it means you performed below the average for your age.

National Percentile CAT4 Rank

The CAT4 National Percentile Rank:
  • tells you how your performance compares to that of other students who took the CAT4 test across the country.
  • is expressed as a percentile, which ranges from 1 to 99.
  • For example, if your National Percentile Rank is 75, it means you performed as well as or better than 75% of students who took the same test nationwide.
  • This is a helpful metric for understanding your relative standing on a national level.

CAT4 Stanine Grade

Stanine, short for “standard nine,” is a way to categorize students’ performance into nine divisions, with each division having specific criteria. It’s a broad categorization that helps quickly assess a student’s performance without needing to refer to detailed scores. The divisions are as follows:
  • Stanine 9: Students in the 90th percentile and above (very high performance).
  • Stanines 7 and 8: Students in the 70th to 89th percentile (above average performance).
  • Stanines 4, 5, and 6: Students in the 30th to 69th percentile (average performance).
  • Stanines 2 and 3: Students in the 11th to 29th percentile (below average performance).
  • Stanine 1: Students in the 10th percentile and below (very low performance).
These components of CAT4 scoring provide a comprehensive understanding of how a student performed on the test. The Standard Age Score and National Percentile Rank offer insight into relative performance, while the Stanine Grade provides a quick way to categorize that performance.
