Realschule or gymnasium were more likely to be respectful and considerate of other peoples' feelings than those attending a comprehensive school. According to this study, gymnasium students were more likely to be classified as "selfless" than students attending any other kind of school and those attending a comprehensive were more likely to be classified "self-serving" than those attending any other type of school. This study has been widely criticised. It has been claimed that character cannot be measured on standardised tests and that students' answers might not reflect their real behaviour. Charges were raised that questions were worded in academic language thus, students attending a comprehensive may not have understood them properly. It has also been suggested that the answers the students gave may have been influenced by social class, that gymnasium students may have been brought up to think they were selfless, while really they were not. Proponents of comprehensive schools stated gymnasium students were phony and elitist while pretending to be selfless. Gymnasium and performance on the TOEFL A study revealed that college-bound students attending a traditional gymnasium did better on the TOEFL than college-bound students attending a comprehensive, but those did better than college-bound students attending an "Aufbaugymnasium," "Technisches Gymnasium" or "Wirtschaftsgymnasium" (the last three schools serve students, who graduated from another school receiving no Abitur and give them the opportunity to earn the Abitur). Defending comprehensive schools Proponents of comprehensive schools often hold the opinion that it is unfair to compare gymnasia and Realschulen with comprehensive schools. While gymnasia and Realschulen often handpick their students, comprehensives are open to all. Proponents of comprehensives also think they lack the most academically promising young people, who have been skimmed off by other schools. They also point out that some comprehensives (such as the "Laborschule Bielefeld" and the "Helene Lange School" in Wiesbaden) ranked among Germany's best schools. Quotas Germany's Left Party introduced a discussion concerning affirmative action. According to Stefan Zillich, quotas should be "a possibility" to help working-class children who do not do well in school gain access to gymnasium. Headmasters have objected, saying this type of policy would be "a disservice" to poor children, that they would not be able to keep up academically. The headmasters have also expressed concerns that children of working-class families would not feel welcome at gymnasia. Wolfgang Harnischfeger, headmaster of a well-known Berlin gymnasium, has stated, It can be noticed in
