DENVER - Federal officials say Colorado is one of several states reporting that its students have mastered math and reading skills when they don't meet tougher federal standards.
The widest discrepancy was in eighth-grade reading, where 87 percent of Colorado students met state standards but only 35 percent met the national mark.
The U.S. Education Department released the report this week.
The report says 86 percent of Colorado fourth-graders met state reading standards but 36 percent met federal criteria.
In math, 91 percent of fourth-graders met state standards while 41 percent met the federal standard. Among eighth-graders, 76 percent met state standards and 37 percent met the national standard.
