The state board shall ensure that a statewide assessment provides the public, the Legislature, the state board, school districts, public schools, and school teachers with:
(1) evaluative information regarding the various levels of proficiency achieved by students, so that they may have an additional tool to plan, measure, and evaluate the effectiveness of programs in the public schools; and
(2) information to recognize excellence and to identify the need for additional resources or to reallocate educational resources in a manner to ensure educational opportunities for all students and to improve existing programs.
