Because of these differences, professional development programs were tailored to the specific needs of the individual school districts. In support of this move to kit-based modules, the Merck Institute established a Resource Center at the company's Rahway, New Jersey facility. Merck Institute staff helped develop criteria for review of materials and assisted school personnel in evaluating and piloting new curriculum unites. The staff continues to advise and guide teachers, working with them to find what best meets their classroom needs. The Resource Center holds hundreds of curriculum modules, books, periodicals, and videos, which teachers and science supervisors can borrow.
Portable planetariums are also available for classroom use.
Also, Merck employee volunteers make frequent use of The Resource Center as they prepare for classroom visits or science fair activities.
