The results of the city’s investigation were summarized in letters sent to state education officials on Friday.
Of the 18 schools the city found to be deficient, officials made a final determination that four were breaking the law.
The city recommended that the state make the same determination about the remaining 14.
Under the law, the city has the power to make final determinations about some private schools but not others.
A spokesman for the state Education Department said officials there were reviewing the city’s recommendations.
City officials also said five other schools they investigated were complying with the law only because of their affiliations with state-approved high school programs.
In the letters summarizing the investigation, officials described visiting schools and finding deficiencies in course planning or proof of teacher training. »
