About CSIU

  • The Central Susquehanna Intermediate Unit (CSIU) is a regional education service agency that prides itself on serving the needs of schools, students, families and communities. CSIU's many programs and services reflect our mission to provide quality education services that help students learn, support teachers in bringing best practices to the classroom, and offer valuable services to school districts.

    As an organization, we ask our staff to look for new opportunities and to be innovative as they strive to understand our clients and their needs. We believe this operating philosophy contributes to our entrepreneurial spirit and enhances our commitment to education and lifelong learning. Over the years, the CSIU developed specialized areas of expertise and has been a pioneer in the areas of technology software and support, and purchasing cooperatives for products and services. Schools in other regions wanted to take advantage of what the CSIU was providing to its local districts. This has benefitted schools in the CSIU region by increasing economies of scale – the greater the number of buyers, the greater the volume of purchases, and the greater the savings.


  • The CSIU's primary service area consists of Columbia, Montour, Northumberland, Snyder and Union counties in central Pennsylvania. It also includes the statistics to the right:
