ReaderBench Model 2

General Description

ReaderBench Model 2 is a simplified version of Model 1 that better handles multi-paragraph compositions, and Model 2 is recommended for current use. Model 2 is an ensemble (formed by averaging predicted quality scores) of the following three sub-models:

• ReaderBench Model 2a
• ReaderBench Model 2b
• ReaderBench Model 2c

Full details of each sub-model are available in the links above.

All of these models used ReaderBench scores on 7 min narrative writing samples ("I once had a magic pencil and ...") from students in the fall, winter, and spring of Grades 2-5 (Mercer et al., 2019) to predict holistic writing quality on the samples (elo ratings calculated from paired comparisons).

More details on the sample are available in Mercer et al. (2019).
