TESSERA GRC unites clinicians, researchers, and healthcare professionals across six continents under a single validated measurement framework. Every member contributes a tile to a global mosaic of adherence evidence.
TESSERA GRC is the global research arm of Scala Carta Foundation, a registered foundation headquartered in the United States. Our mission is to standardize the measurement of medication adherence across all care settings using the MAP (Multidimensional Adherence Parameters) instrument and the ATLAS platform. Learn about MAP and PEACS →
Where most adherence research relies on self-report bias or proxy endpoints, TESSERA members collect structured MAP data through a clinician-administered protocol that takes under three minutes at the point of care. That data feeds a normative global database, enabling cross-country benchmarking that has never been possible before.
Membership is tiered to serve every stakeholder: universities running validation studies, clinics measuring patient populations, individual researchers building their evidence base, graduate students earning their first publication credit, and industry partners seeking real-world adherence data for regulatory submissions.
Every tier contributes to the global MAP normative dataset. The tier you choose reflects the scope of your access, the depth of your data rights, and your role in shaping adherence science.
Post active studies, call for international co-investigators, and discover matching cohorts across 40+ countries. Research Affiliate tier and above can post; all tiers can browse and respond to open calls.
