General Overview
As of Spring Quarter 2025 RTC will be discontinuing the Computer Science Program. We will continue to allow current CSI students to finish their program. We will no longer be accepting new students into the CSI Program.
How long is the program?
- 6 quarters (22 months) with 92 total credits
When do classes meet? Mornings and early afternoons with some online options.
Are summer classes required? Yes, to graduate on time.
In this program, you will learn to design, develop, and test client-server applications. You also will practice more advanced database tasks before completing a capstone project or an internship. This is the applied transfer degree, which is the best preparation for an applied bachelor's program like the BAS in Application Development.
You can learn more about the Computer Science program in our $25 class CCP 046 Bridge to Information Technology Programs.
What does a computer programmer do?
What is the average salary?
$139,160 annually Links to an external site. in the Seattle-Bellevue-Tacoma area. Most computer programmers earn at least $82,530; there is a wide salary range. Jobs with higher pay often require a bachelor's degree.
Who can I contact with questions?
- New students, please visit our Zoom lobby (Links to an external site.) to talk with someone by video chat, or e-mail our advising department.
- For current students, please visit RTC's advising page (Links to an external site and look for the faculty counselor assigned to Computer Science.

Cloud and Cybersecurity Electives
You get to select 15 credits of electives for your AAS-T degree if you started before fall 2023.
You will select 10 credits of electives if you started the Computer Science program in fall 2023 or later.
Note: AMATH 190 will count for 5 credits of electives if you take this math class before you complete transfer math.
You can choose classes from any of the five General Education areas: this is very strongly recommended if you plan to apply to the BAS in Application Development, because that degree requires 60 credits of general education.
You also can use one or more classes from CNT, the other associate program in the Information Technology area of study. If you switched from CNT to CSI, you may have some electives completed already.
