In recent years there has been a heated debate in the international arena about the effectiveness of single-sex education in achieving greater equality between the sexes. However, in Spain, this educational model is still viewed with suspicion by certain sectors, largely due to ignorance about its practical reality, as well as the existence of prejudices that tend to identify it with a type of sexist education that was taught decades ago in certain schools.

The current single-sex school model starts from the idea that there are no assigned roles in society, but that each man and woman must have the same opportunities to be able to freely choose the role they want to play professionally and personally.

A pedagogical model that considers that the differences between the sexes are always enriching and that what needs to be eliminated are the discriminations. A school that aims to eliminate stereotypes, overcoming social inequalities and cultural hierarchies between men and women in force for centuries. In this sense, the current single-sex school is coeducational.

Recent research shows how schools that have introduced specific education techniques for boys and girls (USA, Germany, the United Kingdom, Australia, Spain ...) experience a generalized rise in the academic level and in teaching effectiveness; especially among students who historically have been disadvantaged for socio-economic reasons. Therefore, rejecting the current model of single-sex education, hindering the access to public funding or denying the establishment of public schools of single-sex classes for parents who so wish, assumes a rigid view that is closed to science and pedagogical innovation, which is opposed to the trend set by countries that are managing to overcome the educational crisis and, above all, means denying parents their right to choose the education they want for their children within a framework of constitutionally guaranteed gratuituous. No model, neither single-sex nor mixed, is perfect for all students. The diversity and the plurality of educational models is the force that structures the true freedom of teaching.
