Gradefinity (https://gradefinity.com) is a kind of Blackboard + Scantron LMS alternative that is really targeted in terms of what problems it intends to solve (in-person and online tests, gradebooks, and communication).
Full disclosure: I built it-- I'm very receptive to feedback and feature suggestions though and am looking for pilot schools if anyone is interested in shaping the platform/knows someone who might be.
