On the Progression Benchmark reports you can see the general structure of the tests. There is one test for each of five content domains. Within a domain, there are content areas called sub-domains, and within sub-domains are individual objectives. The top summary report shows scoring on all five domains across the grade levels. Below that, the teacher can drill down to more and more detail, viewing student performance at the sub-domain level (within one domain) and then at an item level (within one sub-domain). The reports show scores on the individual objectives as well as aggregate scoring of all objectives within each grade level, to show the learning progression within a domain.
