The Teaching, Empowering, Leading and Learning Maryland Survey (TELL Maryland) is conducted by Governor Martin O’Malley in conjunction with a coalition of representatives from education, government and business organizations, all of whom believe that it is critical to listen to educators’ views when shaping school improvement strategies.
Policymakers, practitioners, and researchers have long realized that teaching quality is the most important variable for the success of students. Supportive school environments, where educators are valued, trusted, and have the time and ability to collaborate, are necessary for enabling teachers to be successful. To assess whether these conditions are present across Maryland, Governor O’Malley initiated the first-ever statewide total population survey of certificated educators. In partnership with a coalition of state education organizations, the TELL Maryland - Teaching, Empowering, Leading and Learning Survey was created and has been conducted in 20013, 2011, and 2009. 
In the spring of 2011, the second iteration of the TELL Maryland Initiative was conducted. Nearly 46,000 Licensed Educators and Education Support Personnel (ESPs) (51 percent) from across the state shared their perceptions of the teaching conditions in their school in order to examine whether supportive school environments are in place that can maximize teacher effectiveness and student success. Five reports, tools for using results for school improvement planning, and data for the state, all districts and the 869 schools with a majority of their faculty responding are available online here.
In the previous (2009) initiative more than 43,400 educators (62 percent) responded to the survey. State and district results have been available since May 2009 to all educators and the 1,023 schools in which at least half the faculty responded have access to individual school data. An assessment of these schools shows that they are representative of schools across the state.
