The teаching stаff in а suburban middle schооl is cоncerned with the quality of their​ school's teacher-made classroom assessments. This issue has arisen because the district school board has directed all schools to install a​ teacher-evaluation process featuring prominently weighted evidence of​ students' learning—as measured chiefly by​ teacher-made tests. The district office requires teachers to submit all​ students' responses from each classroom assessment immediately after those assessments have been administered.​ Then, in less than 2 weeks after​ submission, teachers receive descriptive statistics for each test​ (such as​ students' means and standard​ deviations). Teachers also receive an internal consistency reliability coefficient for the total test and a p​-value and an​ item-discrimination index for each item. Teachers then must personally judge the quality of their own​ tests' items. The​ teachers' reviews of their​ test's individual items are seen as subjective by almost everyone​ involved, whereas the empirical evidence of item quality is regarded as objective. The​ school's faculty unanimously decides to weight​ teachers' own​ per-item judgments at 25 percent while weighting the statistical​ per-item p​-values and​ item-discrimination indices at 75 percent. Please select the statement that most accurately characterizes the​ test-improvement procedures in this suburban middle school.
