Advanced Spatial Cognition Evaluation (ASCE)

The Advanced Spatial Cognition Evaluation (ASCE) is a 32-item test designed to assess spatial reasoning ability under timed conditions. The maximum time allowed to complete the test is 20 minutes. Each question has one correct answer and 8 multiple-choice options.

The ASCE is a high-range spatial reasoning test calibrated on a high-ability sample, including individuals with verified high IQ scores (such as members of high-IQ societies including Mensa and the Triple Nine Society). It is intended primarily to measure variation in spatial cognition within above-average and gifted populations.

Score interpretation is based on an internal norming sample, and results are mapped onto an IQ-equivalent scale for comparative purposes. The score range extends up to an IQ-equivalent ceiling of 161. Normative data is provided in the table below.

The Advanced Spatial Cognition Evaluation was developed by Randy Myers.
