Complex Spatial Cognition Evaluation (CSCE)

The Complex Spatial Cognition Evaluation (CSCE) is a 28-item test designed to assess advanced spatial reasoning ability under timed conditions. Each question has one correct answer and multiple answer choices.

The CSCE is a high-range spatial reasoning test calibrated on a high-ability sample, including individuals with verified high IQ scores. It is intended primarily to measure variation in spatial cognition within above-average and gifted populations, with an emphasis on more complex spatial transformations and reasoning processes.

Score interpretation is based on an empirical calibration against composite IQ scores, using a regression-based model derived from a preliminary sample. Results are reported on an IQ-equivalent scale for comparative purposes.

The Complex Spatial Cognition Evaluation was developed by Randy Myers.
