It follows an exhaustive process which saw a record number of schools submit entries to be included in the prep school category of the guide.
All entries were judged against an extensive set of criteria, which included a compelling commitment to cricket in the curriculum, facilities, fixture programmes and coaching.
Also considered was how schools kept the game alive during the pandemic, and how they look to ensure cricket remains a central part of school life.
Highfield and Brookham has a strong cricketing tradition and regularly fulfils as many as 230 fixtures in the summer term against rival schools.
The teams feature boys and girls aged eight to 13, with Summer Gratton becoming the first girl to break into the first XI while the under-13 A girls were the first at Highfield to play a competitive T20 game.
Highfield headmaster Phillip Evitt said: “Cricket is an important part of the sporting curriculum here at Highfield and Brookham and we are very proud to have been named one of the top prep schools in the country, recognising our fantastic facilities and coaches.
“It was wonderful last summer for the school, for parents and children alike, to be able finally to welcome back spectators to our competitive match fixtures, and now to be named as the top prep school in Hampshire for cricket really is the icing on the cake.”
