Online Learning Assessments: Are you measuring what matters?

Our Strategic Online Learning Assessments provide a comprehensive, evidence-based assessment of your online course evaluation strategies, ensuring they effectively drive deep learning, meet relevant accreditation standards, and prepare your students for their desired vocations. Assessment reviews generally take 6-8 weeks to complete, include a printable PDF findings report, an optional Zoom presentation to staff and stakeholders, and are based on data measured by Tumbuh's proprietary Comprehensive Assessment Matrix (TCAM). Drop us a message to let us know of your interest, and we'll send you an overview of our approach.
