After the anchor set exercise, scorers are given practice sets that they score independently. One or two sets of 10 to 12 papers (depending on the complexity of the item, with options for larger sets for some items) are identified as practice sets. Each set covers
The papers are randomly ordered within each set. Usually, the first practice set includes examples that may be more straightforward, while more challenging papers often appear in the second practice set.
Upon completion of a practice set, the trainer tallies how many scorers gave the response a "1", a "2", and so on, using a tally form. A scorer on the team may be asked to explain the score they assigned a paper. The trainer provides the correct score to the team, using the practice paper for instruction and discussion. The first practice set is always scored and discussed before going on to the second practice set. Given the complexity of many NAEP items, trainers use all practice sets as part of training.
