Ratings Explained

The rating system here was created at the University of North Carolina to take into account the specific needs of keyboard tray within a university setting.

Evaluators rated each keyboard tray’s keyboard fit, keyboard, mouse, mouse fit, accessories, instructions, and the rater’s opinion. The rating for each category was placed into one of five categories (Very Good, Good, Average, Fair and Poor). The scores were combined and normalized to a percentage of the perfect score (Overall Score).

While evaluating the keyboard tray, the evaluators kept the following criteria in mind:

Keyboard Fit
The “keyboard fit” category refers to the width and depth of the keyboard platform and if the area is sufficient to fit keyboards ranging from the standard keyboard to a larger keyboard like a natural keyboard. Also, “how easy is it to modify to allow for larget keyboards?”
Keyboard

Mouse Fit

Accessories
