What we do

Content Accuracy Checking.  Platform Testing and Engineering.  Specialized Contingent Labor Services.
We perform QC/QA of Mathematics and Hard Science online content and testing platforms for higher education textbook publishers like you.  With you, we develop a Test Plan Matrix to make certain that the functionality and content that you want tested are thoroughly examined so that you can launch your project with confidence.  We field US-based subject matter experts to review content and platform functionality, reporting back to you a detailed analysis of our findings. We assemble SME teams with current, relevant academic expertise, as well as a deep understanding of testing materials and their value to the professors and institutions adopting your titles. 
This translates to more adoptions.  Our exacting attention to the detailed materials on your LMS allows your sales force to drive adoptions with confidence; confidence in knowing the material you are presenting has had the best and most qualified people review, test, and correct it. We have the record to back this up: out of well over a million takes in 2016, there were only five issues found. In other words, that’s a 99.999995 success rate.
We fill the need for related specialized / contingent contractors you may require; yours or those we recruit for you. Our strength is recruiting for and filling short-term, specialized positions such as subject matter experts in various academic disciplines as well as engineering resources with special focus on platform development, deployment, and support.  Of course, we can help with sourcing candidates for more general, long-term employment, as well.
