Pierce College Ft. Steilacoom
We considered about two dozen texts in our adoption process […] Once the finalists were selected, it became clear that the Lippman/Rasmussen text was equal or superior to the others in quality and far outpaced them in cost. The vote of our full-time faculty was, in fact, unanimous.
There’s no reason to use any proxy for quality when we can look at student success directly.

Bellevue College used Stewart (2006-07) and Hoffman (2007-08)
Five instructors taught multiple sections in 2006-07 using Stewart and then multiple sections in 2007-08 using Hoffman.
The student success numbers for these five instructors were virtually identical using each text, but 4 of the 5 had slightly greater student success using Hoffman
