Mission & Team

Our Approach


ACS was established to address a need in the assessment community for design, evaluation, operational support, and quality assurance. These needs align with the founders’ core capabilities and allow them to apply their experiences and knowledge of assessment policy and practice in the education, credentialing, and workforce sectors. The ACS team is committed to providing practical solutions that help organizations ensure the validity, reliability, and fairness of their assessment programs.

Our Story

Currently, Drew is partnering with several assessment stakeholders that are engaging in major redesigns of their existing assessment programs as well as introducing new assessment programs.
