In this article, the authors focus on the coexisting discourses of academic achievement circulating within in the participants’ teaching credential preparation experience. Analysis and interpretation of the participants’ transcripts revealed the presence of two separate, distinct discourses, both of which shared the name academic achievement. The first notion, called “academic progress”, reflects a developmental viewpoint. In this perspective, students are understood to have experienced academic achievement when they demonstrate levels of skill and knowledge more advanced than they held previously. The second notion, called “academic success”, reflects a mastery orientation. In this perspective, students are understood to be achieving academically when they master the knowledge and skills designated for their grade level at an appropriate pace.
