The system may be implemented with any developmentally appropriate curriculum. It blends ongoing observational assessment for all areas of development and learning with performance tasks for selected predictors of school success in the areas of literacy and numeracy. Teaching Strategies GOLD® can be used to assess all children, including English-language learners, children with disabilities, and children who demonstrate competencies beyond typical developmental expectations.
