statistically significant, or unlikely to have occurred<br />

by chance. For the purposes of this study, any result<br />

that has a p-value of less than .05 is considered<br />

statistically significant (as indicated with an asterisk<br />

Results: English Language Arts<br />

As discussed in the in-depth section, there is no<br />

significant difference in achievement on ELA MCAS<br />

testing between LEP students in ELL programs and<br />

LEP students in general education. Of the variables<br />

included in this analysis, including both individual<br />

and school characteristics, MEPA scores and SPED<br />

placement provide the most predictive value <strong>for</strong> student<br />

achievement in English Language Arts. There<br />

is a positive relationship between MEPA scores, a<br />

key measure of English language attainment, and<br />

ELA achievement with MCAS ELA scores tending<br />

to increase as MEPA scores increase. On the other<br />

hand, LEP students in SPED programs tend to have<br />

lower levels of achievement than LEP students that<br />

are not in SPED programs. However, this does not<br />

hold true at the high school level, where there is no<br />

significant difference in achievement between LEP<br />

students in SPED programs and LEP students that<br />

are not in SPED programs.<br />

Two other variables representing individual characteristics,<br />

attendance rate and gender, demonstrated<br />

a statistically significant relationship with MCAS ELA<br />

scores at the high school level. There is a positive<br />

relationship between attendance rate and MCAS<br />

ELA scores, with scores tending to increase as attendance<br />

increases. The relationship between gender<br />

and ELA achievement is also significant, with female<br />

students tending to per<strong>for</strong>m better on MCAS ELA<br />

tests than male students. Neither of these variables<br />

demonstrates a statistically significant relationship<br />

with ELA achievement at either the elementary or<br />

middle school level.<br />

Of the four variables representing school environment,<br />

only two demonstrated a statistically significant<br />

relationship with ELA achievement: Adequate<br />

Yearly Progress (AYP) in ELA and the percentage of<br />

the school’s population that is low income. There is<br />

a statistically significant positive relationship demonstrated<br />

between AYP in ELA and ELA achievement<br />

at the elementary and middle school levels. To<br />

paraphrase, LEP students that attend schools that<br />

have demonstrated AYP in ELA have higher MCAS<br />
