Learning from and with each other is encouraged. However, interacting so as to avoid learning is not tolerated. Any discussion in which no personal notes (or programs) are taken in, and none are taken out, are fine. From such discussions, students should learn the material well enough to construct their notes on their own afterwards. If you are in doubt, the onus is you to discuss the sitation with the professor before hand.

Student Access

Our program is committed to all students achieving their potential. If you have a disability or think you may have a disability (physical, learning, hearing, vision, psychological) which may need a reasonable accommodation please contact Student Access at (503) 494-0082 or e-mail to discuss your needs. You can also find more information at < href=""> Because accommodations can take time to implement, it is important to have this discussion as soon as possible. All information regarding a student’s disability is kept in accordance with relevant state and federal laws.
