Fewer high school students in the United States were ready for college in 2015, say recent test results. Only 37 percent of seniors scored at or above proficiency level in reading. The number of seniors scoring at or above the proficiency level for mathematics fell to 25 per cent. The test is called the National Assessment for Educational Progress, or NAEP. It is also known as the Nation’s Report Card. The U.S. Department of Education has used this test to measure the ability of students in several subjects across the country since 1969. The Education Department collected the scores of 13,200 students for the 2015 mathematics test and 18,700 students for the reading test. The department released the results of those two tests in April. The results showed that average mathematics scores have changed little over the past 10 years.
