Transition courses are temporary courses that academic units may offer so students can complete a degree requirement by enrolling in only part of a semester course. Yes, this type of course will be offered as needed.
For example, a year long sequence of three quarters that becomes a two semester sequence will have a transition course to enable students that missed the first half of the second quarter to complete the first semester without taking the entire semester course. Likewise, there will be a transition course consisting of the last two-thirds of the second semester for a student that has taken the first two quarters of the sequence.
Where two quarter courses have been combined such that material has been dropped, special arrangement will need to be made for a student to enable them to complete the requirements of their quarter-based degree program.
