About Us

Advanced Instructional Systems, Inc., dba WebAssign®, is a privately held education technology company located on North Carolina State University’s Centennial Campus.


Our flagship product, WebAssign, is a flexible and fully customizable online instructional system that puts powerful tools in the hands of teachers, enabling them to deploy assignments, instantly assess individual student performance, and realize their teaching goals.

We are proud of our differentiated approach to improving the teaching and learning experience through an intelligent combination of technology, educational expertise, and superior customer service that provides teachers and students with smart online tools for measured learning.


WebAssign was developed in 1997 and piloted in several classes at NCSU. In 1998, WebAssign became commercially available as a hosted subscription service under the direction of founder and CEO John Risley, Ph.D, a physics education specialist and professor in the Department of Physics at NCSU.

Within a year, WebAssign became the standard in online homework and grading throughout the United States.


Dr. Risley passed away in April 2013, but his passion for using technology to connect students and teachers lives on. As part of his vision, WebAssign became an employee-owned benefit company in 2012, dedicated to enhancing education.


Education is at the center of everything we do at WebAssign. That is why more than 55% of WebAssign employees are current or former teachers, just like WebAssign users. We love talking about the latest education trends and techniques with customers at trade events, on their campuses, and at our own popular annual WebAssign Users Group meeting. We strive to incorporate user feedback into our product. With our historic ties to NCSU and close proximity to UNC and Duke, we attract top talent and can take full advantage of our location in a thriving technology hub.


Adopted by all major academic publishers, integrated with more than 600 science and math textbooks, and enhanced with a robust selection of independently developed original content, WebAssign is easily accessible and widely used by faculty to enrich the teaching and learning experience.

More than eight million students have used WebAssign to submit over one billion answers to homework assignments, tests, and assessments.

WebAssign. Smart teaching. Inspired learning.
