The future of standardized testing: How well can it function as college admissions criteria and academic performance predictor for students in the United States
By: Lit Jhun Yeang,Benjamin
Introduction
Americans place much importance on the idea of providing every citizen with an equal opportunity to vie for limited places in the colleges of their choice. The only way to realize this is to have standardized college entrance examinations which are taken by all applicants in the same manner. Standardized college admissions testing which consists of mostly multiple-choice questions was established in the United States in the early 20th century by the College Entrance Examination Board to make college admissions procedure a uniform one (Zwick, 2002). The following section shows the comparison between hybrid tests and pure achievement tests and the predictive effectiveness of one of the admission tests which is ACT on the academic success of students of various ethnicities in the U.S.
Achievement Tests versus Hybrid Tests
American high school students are very familiar with the two types of standardized tests which are the SAT and ACT respectively. Both of them are hybrid tests which measure a student’s inherent ability and also academic accomplishment. They are also widely used in U.S. to predict a freshman’s success in college. In predicting college grade, Zwick (2002) states that “the correlation coefficient of hybrid test scores is 0.36, compared 0.39 for high school grades and 0.48 for high school grades and hybrid test scores combined.” From the statistical measure shown, it can be deduced that college grades has a weak and positive relationship with hybrid test scores, high school grades or both. Meanwhile, achievement tests are tests which measure students’ obtained skills and knowledge. They therefore measure how much students have learned and how much they knew about a particular subject. They are being viewed as fairer tests because they serve as a better predictor for a colleges students’ success. It is proven that “achievement tests have a correlation coefficient of 0.784 to what a student knows”, although their relationship’ with students’ first year college grades are not revealed, but they do have the potential to replace most of the aptitude tests, which only take students’ innate talent into consideration and not their efforts made and determination shown to do well. The current achievement tests which are available for high schools in the U.S. to select from are the SAT IIs, the International Baccalaureate tests and the Advanced Placement (AP) tests. The SAT II subject tests which last for an hour, provides candidates a variety of subjects to choose from. On the other hand, the Advanced Placement (AP) tests could measure students’ academic performance in college as well as in high school. The only disadvantage that they have is the long testing duration. If they were to be used to measure students’ high school performance, a minimum of 5 subjects tests were to be taken on 5 separate days for more than 10 hours. The next best alternatives of the achievement tests mentioned above are ACT, PLAN and EXPLORE tests respectively which are all hybrid tests. The ACT tests last for about 3 hours, whereas PLAN and EXPLORE tests last for about 2 hours and consist of only multiple choice questions. The 3 tests are offered by the same organization and hence their contents are taken from the same source. This means that students who take 3 of them consecutively in certain duration of time would obtain similar scores for them because the 3 tests have a mutual relationship. In a nutshell, although achievement tests are more time consuming, however they are able to help students to improve their academic performance by displaying them the areas that require more attention. Most importantly, achievement tests are based on and relevant to the high school curricular. 
The Predictive Value of ACT and High School Grade Averages
The ACT Assessment which is vital for college admissions and course selection decisions in the U.S. gauges students’ academic skills and knowledge which were taught and learnt in high school. Students who received a well-versed education in high school or did well in college-preparatory courses will be more likely to obtain higher ACT scores, which will in turn be more successful in their freshman year. However, it is interesting to note that African-American and Hispanic students generally have lower scores on standardized college admissions testing and this situation has caused an allegation that standardized tests are “biased or unfair” (Marklein, 2000). The fact is that they usually do not perform very well in most of the academic achievement measures used to admit students, including high school examinations (Zwick, 1999). This is proven by (Noble, Crouse and Schulz, 1996) who state that African American students typically score lower on Mathematics and English in college than their white counterparts given the same scores in high school Mathematics and English tests. According to (Young and Kobrin, 2001), “students’ actual freshman grade point averages (GPAs) are higher or lower than their predicted GPAs.” Prior research also show that the freshman GPAs of African-American and Hispanic students are lower than that of white and Asian-American students given the same admissions test scores and high school averages. Therefore a study is conducted the investigate the effects of using ACT aggregate scores, high school grade averages or both on the admission rates and freshman year academic performance of African-American, Hispanic and white students.

Results
The study shows that if ACT aggregate scores, high school tests averages or both are used as college admissions criteria, then, without explicitly considering ethnicity, less African-American and Hispanic students would be admitted into colleges compared to white students. Interestingly, this study also reveals that the ACT aggregate scores or high school grade averages predict the likelihood of attaining academic success in college (achieve a freshman GPA of 2.5 and above) more accurately for African-American students than for white students. Furthermore the ACT scores and high school grade averages serve as a less accurate academic success predictor for Hispanic students than for white students. Also, it is important to note that the results which are obtained from this study cannot be applied to all higher education institutions nationwide (Noble, 2003).
Conclusion and Implications
Based on the results shown above, it will appear that it would be hard to maintain the diversity among student populations on college campuses in the U.S. if standardized test scores and high school grade averages continue to serve as college admissions criteria in the United States. However, it is possible for tertiary institutions in the U.S. to admit students who are less academically well-prepared, provided that they will be given extensive remedial classes to ensure that they have a wonderful college experience too. And most importantly, although debates about the usage of standardized college admissions testing are still very intense, more and more SAT and ACT candidates can be seen and about 90% of American colleges continue to use the SAT or ACT examination as a tool to make college admissions decisions.
