Abstract

Test cards include a group of answer indication areas corresponding to the multiple choice answers for each of a plurality of problems for receiving indicia indicating answer responses to the problems. Correct answer information coded on the card identifies predetermined answer indication areas as corresponding to the correct answers for each problem. Sensing of the correct answer code from each test card automatically programs the apparatus with the correct answer for the problems for comparison with the sensed answer response indicia for grading and scoring the answer responses to the plurality of problems of each test card. A visible correct answer code of plural bit positions includes a number of code bit permutations for identification of each of the answer indication areas as a correct answer to prevent deciphering of the correct answer code. Automatic system control and recording of grading and scoring results is provided.
