The results of the trial of the information-based vocabulary assessment instrument on the explanatory text material were captured through the teacher's response questionnaire about the practicality of the developed assessment instruments. The practicality gained was captured through a questionnaire distributed to two teachers who studied Indonesian. The teacher's response questionnaire to find out the practicality of the assessment instruments developed included three sub-components of the assessment, namely aspects of attractiveness, aspects of ease, and aspects of readability. The attractiveness aspect gets a percentage value of 96% in the "excellent" category. Linguistic aspects get a percentage value of 100% with the category "excellent." And the last aspect is the aspect of convenience which gets a percentage value of 85% with the category "excellent."
