Baseline Data<br />

Baseline data are collected following definition of the target behavior and selection of a data collection<br />

method. Best practice dictates that baseline data be collected for at least three sessions. A “session” can be as<br />

short as 15 minutes or as lengthy as a whole school day. The target behavior and selected data collection method<br />

dictate what a session constitutes. For example, if the target behavior occurs several times a minute, three 15-<br />

minute sessions will probably yield adequate baseline data. Conversely, if the target behavior only occurs a few<br />

times a day or once or twice a week, your three sessions may be spread over several days. Baseline data are<br />

collected to assess the frequency and intensity of the target behavior prior to intervention.<br />

Data-Based Intervention Selection<br />

Once the behavior has been clearly defined and baseline data are collected, the next step is to choose an<br />

appropriate intervention or change in method of instruction. It is important to choose an intervention that has a<br />

strong evidence base demonstrating effectiveness and is in published, peer-reviewed research literature.<br />

To meet the criteria of research-based, an intervention should be represented in at least two wellconducted<br />

group-design research studies or multiple examples of single-subject research studies. The studies must<br />

include adequate controls, such as random assignment of subjects to treatment conditions for group models and<br />

multiple-baseline or reversal designs for single-subject models. In order to properly match intervention to student<br />

need, the studies must also include clear identification of the sample characteristics – for example, the behavior<br />

expressed or the diagnosis of the population.<br />

Implementing and Monitoring<br />

Implementation of evidence-based intervention requires attention to detail and consistent professional<br />

development and technical assistance. For example, a school may choose a point system for a student’s target<br />

behavior to reduce talk-outs and increase hand-raising behavior. Once the intervention is implemented, consistent<br />

data collection is needed to determine the effectiveness of the intervention and assess need for adjustment. It is<br />

suggested that within three to five days or sessions, the data will yield information regarding the effectiveness of<br />

the intervention. If the intervention is not working and the behavior is not improving or is getting to be more<br />

problematic, the instructional team should meet to discuss options for modifying and adjusting the intervention.<br />

This is also true of academic targets. For example, if reading fluency was determined to be the target behavior and<br />

an intervention is selected and implemented, then following collection of three progress monitoring data points, a<br />

team can determine whether the intervention is working or whether an adjustment is needed.<br />
