The SASS is administered online during the last week of instruction, to be completed before the final exam. The SPCI is administered as a post-test in class during the last week of instruction.
The SASS results from this semester are compiled below. Values for the mean and standard deviations are given next to the modal response category for each question. Also listed is the percentage of students who have self-assessed themselves as having successfully achieving a learning outcome (responding "average," "above average," or "excellent") as opposed to not achieving success with a learning outcome (responding "very poor" or "below average").

20. Describe key features of terrestrial planets. (86%)
21. Describe key features of jovian planets. (86%)
However, six student learning outcomes were self-reported as being achieved by less than 85% of students, listed below in order of decreasing success:
18. Describe characteristics of the universe a long time ago. (84%)
5. Explain differences between models of planetary motion. (81%)
16. Explain how the speed of light affects observations of distant objects. (81%)
15. Explain evidence for how our Milky Way galaxy came to be. (79%)
19. Explain evidence for how our solar system came to be. (79%)
6. Explain evidence for the heliocentric model of planetary motion. (74%)
Compare these student learning outcomes self-reported as not being achieved (5, 6, 15, 16, 18, 19) with those from previous semesters (fall semester 2014: (7, 21); spring semester 2014: (4, 6, 14, 15, 18, 24); fall semester 2013: (6, 9, 14, 15, 17, 18); spring semester 2012: (6, 18); fall semester 2011: (4, 7, 8)).
Student learning outcomes 10, 11, 12, and 13 for Cuesta College students were directly assessed using the Star Properties Concept Inventory (excluding negative informed consent form responses):
Star Properties Concept Inventory v3.0This semester's SPCI scores are slightly higher than results from 1,100 large research university students that have completed introductory astronomy and earth sciences courses (Bailey, 2007), where the average was 51% (no further statistics provided); and comparable to SPCI results from earlier semesters at Cuesta College.

As per the ACCJC (Accrediting Commission for Community and Junior Colleges), results from this indirect assessment SASS tool, along with the direct assessment SPCI tool will be used for course/program improvement by increasing emphasis on the lowest learning outcomes in instruction in future semesters.
