What is the difference between rti and cbm

The x-axis: The horizontal line on the bottom of the graph represents the number of weeks of your child has been receiving a particular kind of reading instruction. Another dot is added showing how many words per minute he read correctly during the latest assessment. This line is sometimes called a benchmark or aim line. The trend-line provides important information. It can help the RTI team decide what to do next. Here are three possibilities:. A trend-line like this one indicates that not enough progress is being made.

The RTI team needs to try a different instruction method that might work better. The trend-line is moving closer to the goal-line. This kind of trend-line shows a teaching intervention is working and should be continued. The trend-line meets the goal-line.

The rationale is that CBM-R is a brief test of reading fluency, and that fluency approximates is a proxy measure for overall reading competence. We must consider the appropriateness of this logic.

I especially relate to your points about CBM-R changing the goals of teaching, and causing developing students to have negative reading experiences!

A type of formative assessment that can be used in elementary, middle, and high school settings, progress monitoring allows teachers to:.

There are two types of progress monitoring: mastery measurement MM and general outcome measurement GOM , often referred to as curriculum-based measurement CBM. GOM is an effective means of assessing and tracking student reading progress across the year. It is conducted on a regular basis—for example, once a week—by giving a student or a group of students a short test, sometimes referred to as a measure or probe.

Typically, for each of these tests a single reading task e. Because GOM is administered frequently, each test should contain equivalent content. These are referred to as alternate versions. As noted above, reading measures typically use the overall indicator approach , which is one type of CBM. The other type of CBM uses the curricular sampling approach. View Transcript. There are two forms of CBM. The first type of CBM is the curriculum sampling approach. With curriculum sampling for CBM, the annual curriculum is systematically sampled on every alternate test form.

The second type of CBM is called an overall indicator approach. The task is selected because scores correlate with overall performance in that domain. Although they score these reading measures to evaluate student progress, teachers do not use them to assign grades. For this reason, their scores will most likely be low at the beginning of the year and improve over time, an indication that they are learning.
