Leonard Sax, the President of National Association for Single-sex Public Education or NASSPE countered the "Science" article by saying that "ALL the studies cited in the SCIENCE article regarding 'negative impacts' were in fact studies involving a small number of PRE-SCHOOL students attending a COED pre-kindergarten" (capitalized letters in the original). He further said that "these authors provide no evidence for their substantive claim that 'gender divisions are made even more salient in SS settings.' In fact, this conjecture has been tested, and proven false, in multiple studies." Sax cited a study which said that "girls in the all-girls classroom were less aware of 'being a girl' and less aware of gender stereotypes regarding science, compared to girls who were randomly assigned to the coed classroom."
