To earn teacher certification in Georgia, preservice teachers must pass an evaluation titled InternKEYS, which consists of ten professional standards assessing teachers’ pedagogical, subject matter and professional knowledge. Until 2022 Georgia’s teacher preparation programs drew from varied texts and resources to teach these skills and concepts. With grant funding from Affordable Learning Georgia, a team from Georgia Southern University developed KEYS to Teaching Success, a digital OER designed to align directly with the InternKEYS assessment. This column outlines the multiple benefits of making this resource available to future educators. In addition to filling a gap in teacher preparation resources, KEYS to Teaching Success mitigates the high cost of preparing for a modestly-paid profession. It also fosters valuable professional relationships among those working on the development team. Most importantly, as initial assessment data indicate, KEYS to Teaching Success effectively supports Georgia's preservice teachers as they prepare for initial certification.
