  • The Central School District (CSD) Purchasing Department consists of two major areas: Purchasing and Warehousing.  The CSD Purchasing Department has two major responsibilities. 

    • The responsibility to all students, schools, and administrative departments for procuring necessary items of supplies, furniture and equipment, and services in the quality and quantity when they are needed.

    • And at the same time a responsibility to the tax payers for purchasing all approved items at the best possible value while providing adequate records to show this was done legally according to prevailing laws and board policy.
