STEM the acronym for Science, Technology, Engineering and Math disciplines are traditionally low staffed by female employees. The issue may begins at the college level where a study published in PLOS ONE indicates that low confidence levels may be the decisive factor in pursuing further courses. The study was done following 2266 students at more than 100 colleges at the undergrad level. It found that female students who originally planned on degrees in STEM dropped Calculus at a rate 1.5 times higher than males.
