The government's method was to offer private schools four options: (1) continued independence with no aid, (2) integration into the public school system, (3) a permanent «contract of partnership» in which the classes under contract would be
taught according to public school
schedules by teachers under contract to the state, and (4) a «simple contract» of
limited duration in which the designated classes would be
taught by teachers hired by the school but certified by the state.
