In late June of 2020, Let's Go Learn did a significant upgrade. We added formative assessments into our system. As a result, student testing now produces three levels of test data:
- Comprehensive diagnostics: DORA, ADAM, etc. Assessments with multiple scores in them called "multiple measures."
- Sub-test diagnostics: Single individual sub-tests like fractions or phonics, etc.
- Skills/concept testing: Individual quizzes like "short vowel," "adding fractions with like denominator," etc.
Because we now have multiple sources of data and because we need all this data to flow into the same "universal" dataset, the data portal takes all data from the week, Sunday to Saturday, and stores them in a weekly snapshot.
The advantage of this model is as follows:
- All data flows into the same universal dataset.
- Data is based on Active Pulse data model which looks for growth and smoothly out testing dips or false negative scores.
- Teachers do not have to aggregate different types of test data for reporting. In other words, progress monitoring is automatic.
- A weekly reporting paradigm is easier to manage. i.e. week 1 to week 6. Or week 1 to week 8.
The disadvantages:
- Snapshot data is not generated until the end of the week.
