„Concerning cognitive outcomes, it was shown that Waldorf students slightly outperform other Austrian students in reading and science but they perform slightly below the population mean in math. Considering that Waldorf students’ socioeconomic status (SES) is decisively higher than other students’ SES, these results indicate underachievement in Waldorf students as their actual achievement is lower than expected by their SES.“
