What grade or year will my child be in when we move abroad?

Across the main international-school systems, a child's placement is set by age against a cut-off date, not by the grade they just left. As a rule of thumb, the England year number runs one ahead of the US grade number for the same age: a 5-year-old is in US Kindergarten and England Year 1; an 11-year-old is in US Grade 5 and England Year 7. The IB programmes and other national systems then map onto those ages. The catch is the cut-off date, which differs by country and can move a summer-born child a whole year. The core age map (typical ages, English school-year cut-off of 1 September): age 4-5 US Pre-K / England Reception; age 5-6 US Kindergarten / England Year 1; age 6-7 Grade 1 / Year 2; and so on with England running one number ahead, up to age 16-17 US Grade 11 / England Year 12, and age 17-18 US Grade 12 / England Year 13. So a British 'Year 7' and an American 'Grade 6' describe the same 11-12-year-old cohort, not a year's difference in ability. The IB programmes are organised by age band rather than a single grade: the Primary Years Programme covers roughly ages 3-12, the Middle Years Programme ages 11-16, and the Diploma Programme the final two years, ages 16-19 (the equivalent of England Years 12-13 or US Grades 11-12). A school offering the IB will place your child by age into the matching phase. The cut-off date is where families get caught out. England's school-year cut-off is 1 September, so a child must turn the year-group age by 31 August; US states vary widely (cut-offs run from August to as late as December or January); and some systems start the school year in a different month entirely — Japan and much of the southern hemisphere begin in April or January rather than September. A child with a summer or autumn birthday can therefore land a full year apart between two systems. Always confirm the specific school's cut-off and its placement decision in writing before you assume a grade — schools also weigh a child's prior curriculum and readiness, not age alone.
