For example, city and regional planning to architectural engineering.
@jwilli I see you would be a transfer student and there may be different criteria for attempting to change majors if you were accepted into one of the “easier” admits in the CAED dept. with an intention to switch to architectural engineering (a tougher admit). I hope you have asked your question of CP SLO. The University’s goal is for their students to succeed at their chosen majors. You know as a transfer student you will hit the ground running in this department with expectations of performance and strong understanding of the foundations. Hope your strategy works out for you.
My son went to CalPolySLO. Very tough to change into some majors, architectural engineering. It appears that you need someone to leave the major and then the department will select the best candidate, out of all the students that have applied to transfer, to replace that student.
Meet with an academic advisor as soon as possible. Since you want to switch majors within the same college, it will most likely be a slightly easier switch. Also, CRP and architectural engineering are both offered as minors. It might be doable for you to stay in the CRP major and do an architectural engineering minor. Depends what you want to do after you graduate though.
