'summative-assessment-based' originates from English, specifically the compound of 'summative assessment' and 'based', where 'summative' comes from the adjective form of 'summate' (to sum up) and 'assessment' derives from Latin roots meaning 'to sit near, judge', and 'based' comes from 'base' (from Greek/Latin 'basis') meaning 'foundation'.

'summative-assessment-based' developed in recent educational and policy usage by combining the noun phrase 'summative assessment' (an end-of-course or final evaluation) with the adjectival/postpositional element 'based' to indicate something 'founded on' that form of assessment.

Initially, 'summative' referred to the act of summing up or a final summary judgment; over time, compounds like 'summative-assessment-based' evolved to mean 'determined by end-point evaluation' in educational contexts.
