Understanding myON Benchmark Processing


You want to know more about benchmark exams and how they work.


Once a student completes the initial placement (Lexile) test, a baseline Lexile score will be established.  Every 14 days thereafter, once the student has read and completed 5 books or has completed 3 hours total reading time, a purple envelope will appear in the upper left-hand corner of their dashboard indicating that a Benchmark assessment is available.  The student clicks on the envelope to start the assessment.

Once the student starts the benchmark test, the test must be completed during that sitting.  Benchmark tests cannot be exited and restarted at a later date. As the student continues taking Benchmark assessments, parents, through the student portal, and educators, by running progress reports available in myON,  are able to track how the student is progressing in their reading and comprehension skills..  The system continues to track student performance through each benchmark assessment. Below is the student portal display of the Lexile and Benchmark assessments:

Other Considerations

Basically, there are several programs that will measure reading ability and report in Lexiles. Some of these are native tests, which have been developed by MetaMetrics (like the ones in myON). Others are correlations where the test instrument returns a non-Lexile score but is mapped to a Lexile level.  Depending on when the correlation was done, these could be less accurate than a native test. Also, the type of test and how it was delivered could impact the scores. Consider a high-stakes assessment where teachers are watching to make sure a student is focused. Now think about the tests in myON, where there isn’t much pressure to focus and be correct on answers. Or consider a digitally deployed test versus a paper and pencil test. These different environments will create different types of test results regardless of the student ability.

myON works to resolve these differences by having a series of benchmarks after the initial placement exam. One test result will not give you an accurate picture of a student reading ability – instead, the placement test plus ongoing benchmark assessments will be the most accurate view of the student’s ability over time.
