'impartially-assessed' originates from the combination of 'impartial' and 'assess'. 'Impartial' comes from Latin 'impartialis', where 'im-' meant 'not' and 'partialis' meant 'partial'. 'Assess' comes from Latin 'assessus', where 'ad-' meant 'to' and 'sedere' meant 'sit'.

'Impartial' changed from the Latin word 'impartialis' and 'assess' from 'assessus', eventually combining to form the modern English term 'impartially-assessed'.

Initially, 'impartial' meant 'not partial', and 'assess' meant 'to sit beside', evolving to mean 'evaluate'. Combined, they mean 'evaluated without bias'.
