The 2009 Report Card demonstrates fundamental changes to the calculation of Value Added and Achievement scores.

The method of calculating scores and the scale used to determine letter grades have been revised to allow for a transition to new standards and assessments required by the Tennessee Diploma Project.

Two major changes were implemented:

* The baseline year for comparing student achievement has been reset using 2009 test scores instead of 1998 test scores.

* A new grade scale is being used.

The scale used to determine all grades "A" through "F" has been dramatically revised, meaning scores considered to be an "A" in past years may now be a "B" or "C," according to a release from the state.

Education Commissioner Dr. Timothy K. Webb said, "Because we have been on an aggressive path of improvement with the Tennessee Diploma Project, it was necessary to utilize this transition year to change our calculation methods and more accurately demonstrate student progress in an effort to pursue higher standards."

"Part of student success means setting the stage," said Dr. Connie Smith, assistant commissioner of accountability, teaching and learning.

She said, "With the Tennessee Diploma Project and recalibrating the Report Card, we're setting the stage for our students to be more competitive and better prepared for a career or college after high school."

In 2007, the Tennessee Department of Education launched the Tennessee Diploma Project.

The more rigorous curriculum and graduation requirements the TDP call for become effective this year for 9th grade students.
