A new study suggests that girls may be receiving better grades than boys. 

This statistic isn't reflected just in the United States, but all across the globe, said the report. The study, "Girls Make Higher Grades Than Boy in All School Subjects, Analysis Finds," was conducted by American Psychological Association. The report said that "despite the stereotype that boys do better in math and science, girls have made higher grades than boys throughout their school years for nearly a century."

Based on research from 1914 to 2011 across more than 30 countries, "the study found the differences in grades between boys and girls were largest for language courses and smallest for math and science." 

"The female advantage in school performance in math and science did not become apparent until junior or middle school," according to the study. "The degree of gender difference in grades increases from elementary to middle school, but decreased between high school and college."

The researchers, Daniel and Susan Voyer, examined 369 samples from 308 studies, looking at the grades of 538,710 boys and 595,332 girls, the report said. Seventy percent of student grades came from the United States with other grade samples coming from Norway, Canada, Turkey, Germany, Israel, Sweden, the UK, and more. All studies included an "evaluation of gender differences in teacher-assigned grades or official grade point averages in elementary, junior/middle or high school, or undergraduate and graduate university."

The authors wrote, "The study reveals that recent claims of a “boy crisis,” with boys lagging behind girls in school achievement, are not accurate because girls’ grades have been consistently higher than boys’ across several decades with no significant changes in recent years."
