The purpose of the present study is to elucidate if a correlation exist between certain attributes of a school and the choice of Spanish pronouns of adress (tú o usted). In the first place we will look at the choice of pronominal form used to communicate with tutors, be they clients or possible clients of the school. Then we will try to determine the reasons behind this choice. Our working hypothesis is that there are different uses of the pronominal form according to the attributes of the school and the social context. We expect a stronger use of tú as predicted by the « dimension of solidarity » theory. The dependent variables are type of school (public vs partially state funded) the religious nature of the school and its nationality (Spanish vs foreign). The corpus is based upon web pages of 30 public and partially state funded schools located in Madrid. The results are analysed both quantitatively and qualitatively. The results show that a majority of schools use usted in their communication with the tutors, being the only dependent variable that give a more positive result for the use of tú, the nationality of the school. Consequently, the working hypothesis has been rejected.
