Once students have met the Challenge requirements, they are encouraged to continue reading books from the PRC booklists or other sources, covering a range of topics and written by a variety of authors. Regardless of the number of books they read, students can only receive one PRC certificate for completing each Challenge. The new PRC student website allows students to enter more books after they have completed the Challenge. Students who enter more books will not receive a special certificate from the PRC for doing so.
