Boston High School
Boston High School is a selective grammar school for girls in Boston, Lincolnshire. The 11+ entrance exam uses the GL exam board, and there is no interview stage. Parents should aim for 80%+ in practice tests for the pass mark.
If your daughter would rather be known by name than be one face in a crowd, Boston High is worth a look. It is a selective girls' grammar in Boston, Lincolnshire, small enough that teachers know the girls well, with a co-educational sixth form that has welcomed boys since 1992. The school opened in January 1921 with a headmistress, seven teachers and 112 girls — it now has around 800 pupils on its Spilsby Road site on the northern edge of town.
The alumni page reveals a school that quietly produces people who go on to do interesting things. One former pupil became private secretary to Tony Blair; another represented Team GB in rowing; a third captains the national kickboxing team!
What the school sets out to be is a place where every girl can do well in her work and in herself, and where curiosity is taken seriously. It suits a bright, hard-working girl who does her best when she feels seen rather than swept along — the kind who will thrive in a close-knit setting where staff have the time and inclination to notice.

How do you get a place at Boston High School?
A child first needs to reach the required standardised score on both papers of the Lincolnshire 11+ test, set by the Lincolnshire Consortium of Grammar Schools. Girls who reach that standard are then ranked if there are more applicants than places. Priority goes first to looked-after and previously looked-after children, then to children eligible for Pupil Premium, then to those with a sibling already at the school, then by straight-line distance from home to school. There is no catchment boundary, and the school has historically been able to take every girl who reached the required score.
What happens if my child is ill on 11+ test day at Boston High School?
If your child is unwell, do not bring them to the test. Contact the school's admissions team as soon as you can and a later test date can usually be arranged. The same applies for a family crisis or bereavement. Access arrangements, such as large-print papers, a scribe or extra time, are set after talking to your child's primary school and mirror the normal support they already get there. Extra time is only granted where formal evidence sets it out. Declare any special educational needs when you register.
