All trials in PEDro are rated for quality using the PEDro scale and assigned a score. These ratings allow users to quickly and easily identify relevant and valid trials to guide their practices.
The PEDro scale is an 11-criterion instrument used to assess the quality of randomized controlled trials. A total score from 0-10 is calculated. A higher total PEDro score suggests that a trial has higher quality.
While the PEDro scale was developed to evaluate trials on the PEDro database it may be used to score intervention studies across the health sciences.

The PEDro scale checks how well a clinical trial was designed and reported. It looks at things like randomization, blinding, and whether all participants were analyzed. These steps help make the results trustworthy to a researcher.
General classifications for PEDro scale scores are:
These results are best used as a guide, not as the only factor in deciding if a study is high quality. The classification ranges above are used for convenience but have not been formally validated by research.
