Successmaker Alternatives

Like every other district we are being squeezed by the need to provide data for our students progress on state tests. Our district has been using Successmaker for a number of years as an intervention solution. We are also using for differentiation.

Is anyone else using something similar to Successmaker that s more flexible? I want to have students access from both home and school. I am also interested in a program that will run in a web browser.

Thanks in advance for any responses.
