Heckmondwike Grammar School have announced they will hold open days on 22 and 23rd June 2022.
North Halifax and Crossley Heath have yet to announce theirs, but are normally in June. In the meantime, North Halifax have a virtual open day here: https://www.nhgs.co.uk/admissions/school-admissions/open-evening
I would recommend all children in year sitting the test this should attend the open days. Year 4 children may also want to attend.
