University, careers and leadership

Research shows that girls who attend single-sex schools are more likely to achieve well at school, be confident of their academic ability, and aspire to graduate and postgraduate study – all of which are highly advantageous in development of their careers and in achieving their leadership potential. Alumnae of girls’ schools are also more likely to enter male-dominated careers, which is advantageous for their future earning potential.

• A 2018 German study has found that single-sex programs in computer science and mechanical engineering held since 2001 have led to a decrease in the number of female students dropping out of STEM disciplines at German universities. As a result, these programs have helped lead to an increase in the number of females in traditionally male-dominated STEM fields (Busolt, Ludewig & Schmidt, 2018, p. 251).

• On 13 October 2014, Professor Alison Booth, Professor of Economics and a Public Policy Fellow at the Australian National University, wrote in the Sydney Morning Herald that: “Females alone appear to benefit from single-gender classes and they benefit significantly. Women in all-female classes are much more likely to gain a higher degree score and to get a higher-classification degree.”

• Watson, Quatman and Edler (2002) found that girls at single-sex schools had higher real career aspirations than girls at co-educational schools. Career aspirations remained steady and high for many years among girls at single-sex schools but in co-educational schools, ideal and realistic career aspiration scores dropped significantly during the secondary years. Referring to single-sex schools, the researchers concluded that “when girls become the focal point, they rise to a greater level of development than might otherwise ordinarily be the case” (p. 333).

• A 2009 study by Linda Sax based on the UCLA Higher Education Research Freshman Study, which separated single-sex schooling from other influences including socioeconomic background and parental education, found that first-year university students who attended girls’ schools outscored their co-educational counterparts on the SAT (Scholastic Aptitude Test), with mean SAT composite scores (Verbal plus Math) from 28-43 points higher. In addition, 71% of girls from single-sex schools considered college as a prelude to graduate school, compared with 66% from co-ed schools (p. 8).

• Sax also found that graduates of single-sex schools were three times more likely than girls who attended co-ed schools to say they intended to pursue a career in engineering (4.4% vs. 1.4%) and were more confident of their ability in maths (48% rated themselves above average compared with 37% of girls from co-ed schools) and computer skills (36% rated themselves in the highest categories compared with 26% of girls from co-ed schools) (pp. 9-10).

• Sullivan, Joshi and Leonard (2010, p. 25) found that “women who had attended single-sex schools were more likely than coeducated women to gain their highest qualification by age 33 in a male-dominated field“. And a 2011 study by the same researchers found that women who attended single-sex schools earned wages 5% higher than women who had attended co-educational schools (Sullivan, Joshi & Leonard, 2011, p. 329). This economic advantage was accounted for by their superior academic achievement in their O-level examinations at age 16 (p. 328).

• An American study exploring the effects of attending a girls’ high school on labour market outcomes found that women who attended single-sex schools “earn a 19.7% higher wage than women who attended coeducational high schools”, though this wage differential falls to 12.6% after controlling for personal characteristics and selection bias (Billger, 2007, p. 166). Nevertheless, Billger concluded that there was a “substantial” economic return for women who had attended single-sex schools (p. 181).

• An Australian study conducted by Nicole Archard exploring the leadership attitudes of girls attending single-sex schools has found that girls in these contexts have a clear understanding of the ways in which confidence, competition and failure may significantly impact on their capacity as leaders, by inhibiting or facilitating them in their pursuit of leadership roles (Archard, 2012, pp. 189-190). Girls taking part in the study believed their single-sex school was teaching them to be a strong, independent leader and predicted that their confidence would be worse in a mixed sex environment where they may or may not be encouraged to pursue leadership roles (p. 196).
