Perry Green's schools are good, provided you're happy for "local" to mean a car journey. About nine in ten graded schools in the county are rated good or better. There's a primary within a quarter of an hour. The secondary is a different matter. The grades are the easy part here and the distances are the hard part.
Hertfordshire has 227 schools with a published Ofsted grade, and 203 of them are rated good or outstanding, close to nine in ten. Forty are outstanding, 21 require improvement and three are inadequate. Another 226 settings in the county have no published grade yet. They're simply ungraded, which says nothing either way about their quality. Those counts cover the whole of Hertfordshire, a county with plenty of large towns, and a hamlet of this size borrows its schools from the same pool as everyone else.
A good county average says little about where your child actually ends up. Hertfordshire County Council allocates places under its published admissions rules, so living near a school doesn't secure a place there. In a scattered rural parish, how far you live from the gate can matter in ways a postcode doesn't make obvious. Parents in Perry Green tend to learn the admissions criteria in more detail than they ever learned the council-tax bands.
The primary named for this corner is St Andrew's CE Primary School and Nursery. The Department for Transport's 2019 modelling puts the nearest primary about 15 minutes away on foot and about eight by car. St Elizabeth's School and St Elizabeth's Centre are the other two names on the local list. Secondary is where the geography bites: the same 2019 modelling puts the nearest secondary about 16 minutes away by car, about 44 by public transport and about 80 on foot. Before committing to a house, get the council's home-to-school transport rules for your exact address, because a child who walked to primary in a quarter of an hour will need either a school bus or a parent with a car for the next seven years.
The quality of schooling is one of Perry Green's real strengths, with a county where nearly every graded school is good or better. The cost is the drive, and in secondary years that drive comes twice a day.
