High-stakes standardized tests standardize which knowledge is assessed, and because consequences are tied to their results, they have the impact of standardizing classroom content, teaching, and learning. The result is that students whose cultural identities do not fit the standardized norms created by test-based must either adapt or are left out of the curriculum and the classroom. This happens in a few key ways. First, as schools face increased pressure to raise test scores, curriculum content that embraces the diversity of student history, culture, and experience gets pushed out. In turn, this standardization of content limits the diversity of teacher and student identities expressed in classroom pedagogical experiences. Finally, given the disparate racial achievement on high-stakes tests, students of color face more intense pressure to perform, while at the same time their educational experiences become increasingly restricted and less rich than those of affluent, whiter students. Additionally, even though educational research has consistently shown that high-stakes testing correlates most strongly with the socioeconomic backgrounds of students and their communities, policymakers and many educators presume that these tests are offer objective measurements of individual merit. This mistaken belief ulitmately serves to hide and justify existing inequalities in the United States under the notion of individual achievement. The overall result being that high-stakes, standardized tests reproduce educational inequalities associated with race and class in the United States.
