Many Going to College Are Not Ready
Only about half of this year’s high school graduates have the reading skills they need to succeed in college, and even fewer are prepared for college-level science and math courses, according to a yearly report from ACT, which produces one of the nation’s leading college admissions tests.
The report, based on scores of the high school graduates who took the exam, some 1.2 million students in all, also found that fewer than one in four met the college-readiness benchmarks （基准）in all four subjects tested: reading comprehension, English, math and science.
ACT sets its college-readiness benchmarks — including the reading comprehension benchmark, which is new this year—by correlating（联系）earlier students’ ACT scores with grades they actually received as college freshmen. Based on that data, the benchmarks indicate the skill level at which a student has a 70 percent likelihood（可能性）of earning a C or better, and a 50 percent chance of earning a B or better.
Among those who took the test, only 51 percent achieved the benchmark in reading, 26 percent in science, and 41 percent in math; the figure for English was 68 percent. Results from the new optional ACT writing test, which was not widely taken this year, were not included in the report.
About 40 percent of the nation’s high school graduates took the ACT, and the average overall score was unchanged from the year before. Minority students make up 27 percent of all ACT test takers. Besides, there are also other worrying trends in the ACT report as well, including a continuing decline in the percentage of students planning to major in engineering, computer science and education.
