Comparison of data-collection methods in a behavioral intervention program for children with pervasive developmental disorders: a replication.

The team copied an earlier study to see if two ways of scoring lessons give the same answers.

They taught kids with autism new skills and wrote down results two ways.

One way logged only the first try each day. The other logged every try.

Both ways spotted mastery on the same day.

Skills stayed strong no matter which way the staff counted.

First-trial notes were enough.

Fuller et al. (2018) pushed further. They asked, "How high should the mastery bar be?" Ninety percent beat lower cut-offs for keeping skills.

Bulla et al. (2026) also copied past work. They showed that fewer, timed trials can teach faster than free-flow drills.

Anonymous (2024) tested a phone app. It gave steady numbers, backing the idea that lean data can still be clean.

You can save minutes every session by logging just the first try. Those minutes add up to more teaching time. Try it next week: pick one program, record only trial one, and see if mastery dates stay the same.
