The author has taken the liberty of borrowing from past candidate (and president) Bill Clinton's "War Room" mantra to suggest that those who are working toward preparing schools for online assessments of Common Core State Standards (CCSS) might be forgetting the most important element in the process: the classroom teacher. The author argues that the Common Core standards and new online assessments need more than technology readiness--they need teacher readiness. He stresses that states and districts need an all-out collaborative planning effort among the assessment, curriculum, and technology staff to ensure that teachers and other instructional staff are ready for the new approach to assessment. Collaboration is the key in the planning effort as each department has a lot to bring to the proverbial table. Although each teacher readiness plan will be somewhat different depending upon a state's or district's circumstances, some crucial steps must take place in all planning. The author discusses steps that could ensure teacher readiness.
