* This item was also used in the 1992 National Adult Literacy Survey (NALS).

In the young adult literacy survey (YALS), both people and tasks (items) were given scale scores. For instance, a person with a skill level of 210 would have a probability of .80 of performing a task that has a difficulty level of 210 (see item above). All of the sample tasks presented on pages 100 through 112 show the task difficulty of the item and the probability that people with different skill levels could perform the item. In the item above, the task difficulty is 210, and people with a 210 skill level have an 80% probability of being able to perform the task. However, other people with lower skill levels may also be able to perform the task, though with lower probabilities. In the item above, people with skill levels of 150 have a 32% probability of being able to perform the task that is at the 210 difficulty level. People at the 200 level have a 74% probability of performing the task. People at the 300 skill level have a 99% probability of performing the 210 difficulty level task.
