PEG operates on the principle that "good writing can be predicted" by analyzing specific linguistic features. The system uses a two-stage process: Today, it is managed by Measurement Inc
: In the 1990s, as computerization became feasible, PEG was used for large-scale testing programs like the GRE and NAEP . Today, it is managed by Measurement Inc. and powers platforms like ERB Writing Practice . How the Algorithm Works Key Analytical Features
: New essays are analyzed for these same features—known as "proxies"—and a score is calculated using the established statistical model. Key Analytical Features
