Contrast Type 1 & 2<br />
• Contrast 1: Test <strong>for</strong> NCLB effect nationally<br />
– Compare student achievement in public schools with<br />
private schools (both Catholic and non‐Catholic)<br />
• Contrast 2: Test <strong>for</strong> NCLB effects at the state level<br />
– Compare states varying in proficiency standards.<br />
• States with higher proficiency standards are likely<br />
to have more schools fail to make AYP and so more<br />
schools will need to “re<strong>for</strong>m” to boost student<br />
achievement
