In this article we are talking about the early development of the educational process in one of England's North American colonies. Pennsylvania attracted many immigrants from Europe by its religious freedom. Moving to a new land, Europeans from different countries brought their way of life, including various systems of education. Therefore, at the end of the beginning of the XVII-XVIII centuries there were several different types of schools. The national education system, which appeared only in the XIX century has absorbed much of the colonists created.
Recently there have been widely spread models (classifications) of educational institutions (schools) based upon regularly collected statistical data and a presupposition that all the standard indices incorporated in those models have the same meanings concerning to every possible school. The article questions this presupposition.
