I'm not sure how applicable the key stage point is here. Children generally have little to no exposure to the fact they are part of a key stage or how that affects them until they get to the GCSE/A Level stage where clearly it's impossible to not feel the exams looming. Key stages are more a strategy thing for DfE/Local Authorities.
