I don't understand the meaning of "good practice visits" in the following sentence:
The report is also informed by good practice visits to 11 primary schools, one secondary school and two sixth-form colleges, but the evidence from these visits is not included in the proportions quoted in the report. (Mathematics: made to measure by OFSTED.gov.uk)
Does it mean "the right way of visiting schools" provided information for the report?
If I make any mistakes in English, please let me know!
Yes.
They are, I think, visits designed to make sure people are doing things the right way.

No. It has nothing to do with formality. If you are supervising somebody you want to make sure they are doing things the right way. (The way you want them to do those things.)
P.S. You left out an article.

You'll hear "best practice" more often in connection with working practices.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
The phrase "good-practice visits" is evidently a term used by the OFSTED government office. It's jargon which is meaningful to people who work in that office and, presumably, in the schools it regulates, but not necessarily to others.

Both terms good practice and best practice seem to me to be widespread management-speak nowadays.
