.<br />

<strong>The</strong> variance on the average score of the standardized English achievement of<br />

<strong>HSA</strong> may be modeled with the six school-level predictors -- high school’s percentage<br />

special education (HSSPED), high school’s percentage of ELL students (HSELL),<br />

high school’s percentage of students of poverty (HSFARMS), high school’s<br />

percentage of students attendance (<strong>HSA</strong>TTEND), high school’s percentage of highly<br />

qualified teachers (HSHQT), and number of 9th grade students suspended<br />

(Suspended). Incorporating those variables led to the following changes to the schoollevel<br />

equations:<br />

β oj<br />

= γ oo<br />

+ γ o1<br />

*( HSSPED) + γ o2<br />

*( HSELL) + γ o3<br />

*( HSFARMS) + γ o4<br />

*( <strong>HSA</strong>TTEND) +γ o5<br />

*( HSHQT) + γ o6<br />

*( Suspended) + u oj<br />

where γ oo<br />

is the grand mean for <strong>HSA</strong> English reading score (overall intercept); γ o1<br />

is<br />

the relationship between high school’s percentage of students taking SPED and <strong>HSA</strong><br />

English score; γ o2<br />

is the relationship between high school’s percentage of ELL<br />

students and <strong>HSA</strong> English score; γ o3<br />

is the relationship between high school’s<br />

percentage of students taking FARMS and <strong>HSA</strong> English score; γ o4<br />

is the relationship<br />

between high school’s percentage of students attendance and <strong>HSA</strong> English score; γ o5
