[U5Q] Rodney is accumulating hours toward his BCaBA certification, and his supervisor is assessing his observation skills.

For the next 5 days, Marell reads between 4–9 pages and meets the minimum requirement on 4 out of 5 days. Ricardo then sets 7 pages as the minimum number of pages Marell needs to read daily. Marell continues to meet the minimum number of pages read by reading between 7–15 pages a day. Ricardo then sets 12 pages as the minimum number of pages Marell needs to read to earn a daily reinforcer. What should Ricardo consider when using a changing criterion design?
