We had 186 pre-service teachers visually analyze single-case graphs, representing an intervention effect, a baseline trend, both, or no change at all. The presence of a baseline trend increased type I errors from 5% to 25%. Inter- and intra-rater reliabilities were low, particularly for graphs including a baseline trend.
