Evaluation and Development Tools

Here are some free tools and browser toolbars that web developers may use to check a website’s accessibility according to international standards and guidelines.

As of Fall 2015, Rutgers has received proposals from several vendors who supply website compliance and evaluation solutions. We are forming a small group of evaluators who can help us narrow down the pool and ultimately make a selection that will benefit those who develop, maintain, and support websites.
