Yes. If the number of course modifications result in an increase in the proportion of program courses delivered online to 50% or more of the program courses, the program will become designated a distance learning (DL) program as defined by WSCUC. At the point where programs reach the 50% threshold for online courses, WSCUC requires a Substantive Change Review. In this review, WSCUC staff review a program screening form to determine whether a substantial departure from the original program has taken place. If the WSCUC staff deems that the change does not require review, the program is approved and added as a DL program on the NPS program list in the WSCUC portal in order to achieve and maintain accreditation. 

The ALO has developed an intake form to assist with this process.
