A stanine score represents a student's performance on a scale from:

A stanine score is designed to simplify the interpretation of an individual's performance on a standardized test by placing it within a nine-point scale. This scale ranges from one to nine, with one indicating the lowest performance and nine representing the highest. Each stanine score corresponds to a specific range of percentiles, allowing educators and others to quickly assess where a student stands relative to their peers.

The nine-point scale also serves to normalize scores across different assessments, making it useful for comparing student performance in various contexts. Additionally, the stanine scoring system is helpful in identifying strengths and weaknesses in a student’s academic performance, facilitating targeted interventions and instructional strategies. Hence, the correct answer reflects these well-established principles of the stanine scoring system.
