Shrewsbury Prepatoria goes on to say that parents "can forget about the need for expensive holiday clubs", adding that school fees of £6,540 a year will save parents thousands of pounds in childcare fees.
Taking term time holidays is illegal at state schools, and parents can be fined by local authorities for their children's "unauthorised" absences.
However, families with children at private schools can go on holiday during term time without fear of being fined.
"Who realistically (except for teachers) actually receives 13 weeks holiday per year? Certainly not our parents. We knew that there were strong levels of parental demand for an alternative approach to schooling in the local area," Jane Smalley, the school's founder and head teacher, told The Times.
"What parents coming to us have so strongly embraced is a combination of the educational philosophy that we offer, the family-centric ethos of the school, the quality of our teaching and, of course, the flexibility to holiday as a family at a time to suit them."
