Grimsdell, Mill Hill Pre-Prep, is situated in the Green Belt on the boarders of Hertfordshire and Middlesex, just ten miles from Central London. A part of The Mill Hill Education Group and set in 160 acres of beautiful grounds, we make extensive use of the outdoors in all subject areas, and Forest School has a firm place within our curriculum. We provide a happy, secure and rich learning environment for boys and girls aged 3 to 7. Belmont, Mill Hill Preparatory School, is less than a quarter of a mile away and educates pupils from age 7 to 13, the majority of whom move on to the senior school – Mill Hill, which educates boys and girls from age 13 to 18.
We pride ourselves on the delivery of our creative curriculum which seeks to embed dynamic experiences into the children’s learning. Grimsdell children are inspired to learn while being encouraged to explore and enjoy their childhood. Our pupils learn through hands-on experience with the support and guidance of professional and caring staff aided by excellent resources and equipment. Our approach combines traditional skills of reading, writing and mathematics with the breadth and balance offered by an enhanced Early Years Foundation Stage and KS1 Curriculum. Every pupil will benefit from the many opportunities offered at Grimsdell, including lessons from specialist teachers in Science, Technology, French, Drama, Music, PE and Forest School. Our Nursery children enjoy a hybrid learning environment, spending half their day in the traditional classroom environment – with access to the outdoor early years play area – and half their day in our on-site Nursery Forest School, complete with outdoor classroom.
The school is housed in a large Victorian building with its own secure play areas and adventure playgrounds, taking advantage of further facilities on the Mill Hill site including a Forest School area, sports fields, swimming pool and theatre.
We have two main entry points at 3 years old (Nursery) and 4 years old (Reception), with occasional vacancies occurring in Years 1 and 2. It is expected that most children will pass to Belmont at the end of Year 2.
Charitable status. The Mill Hill School Foundation is a Registered Charity, number 1064758. It exists to provide education for boys and girls.
