According to Dr. Wiliam, the only way to raise student achievement is through sustained investment in teacher professional development focused on minute-to-minute, day-by-day formative assessment. Since effective implementation of such formative assessment requires considerable changes in what teachers do daily, it also requires the formation of building-based teacher learning communities (TLCs) in which teachers are held accountable and provide support for one another.
