Prentice Hall offers online resources for textbooks in career and technology, language arts, mathematics, world languages, science and health, social studies, and specialized AP and other advanced programs. Resources are grouped by specific textbook and chapter.

Resources offered included self-tests, Internet activities, references and teaching links, and answer keys for selected problems. Students can access the resources for a book by entering a code, usually found in the front cover, into the Prentice Hall website and making an account. Teachers also have access to these resources, sample curriculum plans and a community of educators, and they can view which students have accessed the site and their scores on self-tests.
