| Exhibit 8. Improvement Needed to Reach 100 Percent Proficiency by 2013-14, by Level of Difficulty of State Academic Achievement Standards, for 8th Grade Mathematics |
|---|
|
| Exhibit reads: States that had set higher proficiency standards than other states (measured relative to NAEP) had an average AYP starting points of 19 percent and needed to increase their percentage of students achieving at the proficient level by 81 percentage points in order to reach NCLB’s goal of 100 percent proficiency by 2013-14. Note: States were required to set starting points for measuring progress towards the goal of 100 percent proficiency, based on the percentage of students achieving at the proficient level in 2001-02, either for the lowest-achieving student subgroup in the state or for the school at the 20th percentile of enrollment among schools ranked by their percent proficient (whichever is higher). Sources: Study of State Implementation of Accountability and Teacher Quality Under NCLB (n=34 states). Categorizations of states as having higher or lower proficiency standards are based on data from the National Center for Education Statistics (2007), Mapping 2005 State Proficiency Standards Onto the NAEP Scales (NCES 2007-482). Data on average starting points are from State Accountability Workbooks and State Educational Agency Websites. |
