As a result of the evaluation of 1085 school absences in a retrospective study at the Aarau Technical School, it was found that frequency of absences was significantly (p less than 0.01) less in summer with 2.3 percent (boys) and 2.0 percent (girls) missed lessons than in winter with 3.5 percent (boys) and 3.2 percent (girls). There were medical reasons in 58.7 percent; every tenth case was an accident. A comparative study in 1495 schoolchildren aged 6-16, in the Aargau showed that in this collective, there was an average of 1273 school absences per month, so that about 1.8 percent of the monthly school time was lost. A further comparative study in the City of Zurich revealed that about a third more time was lost than in the country.
在阿劳技术学校进行的一项回顾性研究中，对1085次学校缺勤情况进行评估后发现，夏季的缺勤率显著较低（p小于0.01），男生的缺勤率为2.3%，女生为2.0%，而冬季男生的缺勤率为3.5%，女生为3.2%。58.7%的缺勤是由医疗原因导致的；每十例中有一例是意外事故。在阿尔高州对1495名6至16岁学童进行的一项比较研究表明，在这个群体中，每月平均有1273次学校缺勤，因此每月约有1.8%的上课时间被浪费。在苏黎世市进行的另一项比较研究显示，该市损失的时间比农村地区多约三分之一。
