In a Wall Street Journal (3/12, Arguelles, Subscription Publication) op-ed, Randolf Arguelles, who heads a test prep center and reviewed applications to UC Berkeley for eight years, argues that the SAT is the only objective measure of a prospective student. Further, Arguelles argues that changing the SAT will extend, not mitigate, the socioeconomic education gap by privileging test takers from suburban districts. Arguelles concludes that the old SAT provided a fair and unbiased means of measurement, and proposed changes will underscore disparities.
