Online Learning: Are you measuring what matters?

Our Strategic Online Learning Assessments provide a comprehensive, evidence-based assessment of your online course assessment and 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 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.
