These changes are worth making whether or not Tennessee is awarded a RTTT grant - and because it already has the longest-running and most sophisticated value-added system in the country already in place, many of the costs of these changes have already been incurred.
Tennessee was the first state to adopt a value-added assessment system, which allows you to see what schools, or individual teachers, contribute to the academic advancement of their students. TVAAS was implemented 10 years before NCLB, so we have experience and a rich set of historical data to work with. This is reliable data - far more reliable than classroom observations, which are a poor choice for tracking the connection between teaching and measurable learning outcomes.
