Bandar Bener Meriah; describe how the feasibility of
authentic assessment instrument on HOTS-based exposition
text, and describe students’ learning outcomes by using the
authentic assessment instrument on HOTS-based exposition
text. This research referred to the development model of Borg
& Gall. The findings of the study showed that: (1) developing
the authentic assessment instrument on HOTS-based
exposition text was based on research and preliminary
information collection, planning, developing initial product,
design validation and evaluation, product revisions,
assessment and suggestions from language teachers and
students, revisions, individual trials, revisions, small group
trials, revisions, limited field trials, revisions until the product
was valid and feasible to use; (2) The average percentage of all
sub-components from the validation of design experts was
81% with the criteria "very good”. The average percentage of
all indicators from the experts’ evaluation validation for the
instrument in the form of description was 95.7%, for multiple
choice instruments was 94%, and for psychomotor
instruments was 86, 83%. All assessments from evaluation
experts were in the criteria of "very good”. The teachers'
