There may be some truth to this. School reformers find it harder to raise reading scores than math scores.

In Raising Scores, 1 2 3 Is Easier Than A B C

TROY, N.Y. — David Javsicas, a popular seventh-grade reading teacher known for urging students to act out dialogue in the books they read in class, sometimes feels wistful for the days when he taught math.
A quiz, he recalls, could quickly determine which concepts students had not yet learned. Then, “you teach the kids how to do it, and within a week or two you can usually fix it,” he said.
Helping students to puzzle through different narrative perspectives or subtext or character motivation, though, can be much more challenging. “It could take months to see if what I’m teaching is effective,” he said.
Educators, policy makers and business leaders often fret about the state of math education, particularly in comparison with other countries. But reading comprehension may be a larger stumbling block.
Here at Troy Prep Middle School, a charter school near Albany that caters mostly to low-income students, teachers are finding it easier to help students hit academic targets in math than in reading, an experience repeated in schools across the country.
Students entering the fifth grade here are often several years behind in both subjects, but last year, 100 percent of seventh graders scored at a level of proficient or advanced on state standardized math tests. In reading, by contrast, just over half of the seventh graders met comparable standards.
The results are similar across the 31 other schools in the Uncommon Schools network, which enrolls low-income students in Boston, New York City, Rochester and Newark. After attending an Uncommon school for two years, said Brett Peiser, the network’s chief executive, 86 percent of students score at a proficient or advanced level in math, while only about two thirds reach those levels in reading over the same period.
“Math is very close-ended,” Mr. Peiser said. Reading difficulties, he said, tend to be more complicated to resolve.
