Special Awards

Special Awards are given by individuals, and local, state, and national organizations.  The Special Award donors establish the criteria for their awards and often provide their own judges.  Awards might include monetary gifts, treasury bonds, gift certificates, plaques, trophies, journal subscriptions, scientific equipment, tours of facilities, and special opportunities for students.
