This study compares and projects whether public high schools in Johnson and Wyandotte counties in Kansas will be successful at achieving their 100% proficiency reading and math Adequate Yearly Progress (AYP) goals by 2014 as mandated by No Child Left Behind (NCLB). These counties were chosen for the purpose of contrasting their school's different demographics in economically disadvantaged and minority students, as well as their recent proficiency percentages on reading and math assessments. Projections for low medium and high AYP growth are made by replicating a study about the impact of AYP on schools in the Great Lakes States (Wiley et al., 2005) and by using an All Student Approach. The study finds that no school will meet AYP under low or medium growth projections. With high growth projections, the Wiley Approach finds one school will meet the 100% proficiency and the All School Approach finds all but one of the high schools will meet the 100% proficiency or be Safe Harbor eligible by 2014. This study concludes that most schools will be labeled as failing, while the vast majority of students will be proficient. The study questions whether 100% proficiency is a realistic goal.
