Curriculum Based Assessment Examples

Getting CBAs to Actually Work in a Real Classroom

Most people treat Curriculum Based Assessments like they're supposed to produce clean data on the first try. They don't. I spent three years watching teachers try to force them into standard grading routines, and the ones who made it stick did it by treating CBAs as a progress-monitoring tool, not a summative event. The method is straightforward, but the implementation has enough quirks that skipping the groundwork usually means your data becomes noise within six weeks. A Curriculum Based Assessment is a standardized measure of student performance against grade-level expectations, administered repeatedly over time so you can track growth. It's different from a unit test because the content isn't taught for a single assessment window. You're measuring baseline, then re-measuring at intervals. The examples you find online usually fall into three buckets: curriculum-embedded assessments tied directly to what was just taught, independent curriculum-based measurements like DIBELS or AIMSweb probes, and dynamic CBAs where the difficulty is adjusted in real time based on student response. I need to walk through one specific problem that comes up constantly. You administer a math CBA in October and every kid scores in the expected range. By February, the same probe shows barely any growth, and you realize the initial scoring criteria were too generous. The workaround I ended up using was recalibrating the rubric mid-year using anchor papers from the district's moderation cycle. Instead of trying to force the old scale to work, I pulled five students from different performance bands, had the team score their work independently, then compared those scores against the original rubric. The drift was real. We adjusted the scale and kept both versions on file so we could calculate growth across the changed boundary. It added about forty minutes to the planning session but saved us from writing off two months of data as a failure.

Curriculum Based Assessment Examples That Actually Work

Here are some concrete examples from different subjects, along with what the administration actually looks like in practice. Reading fluency with comprehension monitoring: The student reads a grade-level passage aloud for one minute. You score oral reading accuracy and fluency, then ask two literal comprehension questions. The example probe from Read Naturally or the DIBELS maze format follows this pattern. What people miss is that the comprehension piece often gets dropped because it adds time, but without it you can't tell if a student is reading automatically or just decoding words faster without meaning. Keep the comprehension check. Two questions max. If a student scores above 90th percentile on fluency but answers zero comprehension items correctly, that's a red flag worth investigating before the next intervention cycle. Math computation probes: A student works through a set of grade-level problems for three minutes. You count correct answers, not effort. The example from Math AIMSweb or the Florida Diagnostic Assessment uses timed sets of ten to fifteen problems. The nuance most people skip is how you handle incorrect answers. Partial credit destroys the integrity of a CBA. Each problem is scored correct or incorrect. Full response only. It feels harsher than it is because the repeated measures design smooths out the outliers over time. If a student gets 18 correct out of 25 problems in three minutes in November and 22 correct out of 25 in March, that's growth even though both scores might look mediocre in isolation.

Writing samples scored with a holistic rubric: The student writes for ten minutes on a prompt aligned to the current unit. You score using a rubric with descriptors for content, organization, and conventions. The example from the WriteToLearn or FAST PBIS assessment framework uses this format. The tricky part is inter-rater reliability. Two teachers scoring the same piece should land within one point of each other on a five-point scale. If they don't, you need to recalibrate using anchor essays before proceeding. I've seen whole schools skip this step and end up with CBA data that looked consistent because the scoring criteria were vague enough to mean anything. Vocabulary and syntax checks embedded in science or social studies: Rather than a standalone test, the CBA becomes a short check for key term usage during regular instruction. The example format appears in curriculum-embedded assessments from Amplify or EDSITEX. You give students a concept they just encountered and ask them to use the term correctly in context. This one gets pushed back because it feels less formal than a scantron, but it gives you weekly data points instead of monthly ones, which matters when you're trying to catch a regression early. The main bottleneck with CBAs is that they require consistency in administration. If you switch probe versions between measurement occasions without a linking study, you can't compare scores across time. I once worked with a building that rotated through three different math CBA publishers over one year and reported that overall growth had stalled. The growth hadn't stalled. The instruments weren't equivalent. It took about two weeks of cross-walking percentiles across the three versions to prove it.

Another pitfall is assuming CBAs can diagnose learning disabilities on their own. They can't. They tell you whether performance is decreasing, stable, or increasing relative to a curriculum standard. When a CBA shows a flat line over four to six weeks despite implemented interventions, that's the point where you move into a comprehensive evaluation. The data supports the next step. It doesn't replace it. If you want a starting point for building your own sets, the free probes from the National Center on Intensive Intervention and the DIBELS 8th Edition website are the most reliable open resources. They come with scoring guides and administration videos, which matters more than you'd think because a two-minute deviation in timing can change a student's classified performance band by a full percentile.
