IntroductionThe last decade of K-12 education has
evolved to accommodate federal and state policies on accountability through measuring student achievement with standardized tests. Performance standards have been established for all students, with stratification on certain variables, e.g. language proficiency.
Literature Review• Last decade has seen an increase in the
importance of accountability, both nationally and at the state level• No Child Left Behind (2002)• AZ LEARNS (2001)• Proposition 203 (2000)
• State level assessments instituted • AIMS• AZELLA
Literature Review• Arizona is among outlying states for
numbers of ELL students served in education system
• In 2004• Arizona; 155,789• California; 1,591,525• Florida; 299,346• Illinois; 192,764• New York; 203,283• Texas; 684,007• Puerto Rico; 578,534
Literature Review• Arizona is among outlying states for
numbers of ELL students served in education system
• In 2004 - Arizona; 155,789• ELL population steadily growing,
particularly in states with previously low numbers.
• Reports of persistent gaps in ELL and non-ELL performance• Genesee, F., Lindholm-Leary, K., Saunders, W., & Christian, D.
(2005)
Literature Review• Two primary factors likely to influence ELL
assessment• Curriculum/Instruction
• Could investigate these two individually• Not investigated in the current study• Wright (2005) – Discusses approaches of
institutions with ELL programs and/or ESL accommodations.
• Assessments
Literature Review• Research has focused on three major factors
likely to influence ELL assessment• Curriculum/Instruction• Assessments
• Huempfner (2004) – based on assumption that same assessment is valid for bilingual and English speaking students
• Valenzuela (2005) - High stakes testing not appropriate for ELL students
Purpose of the StudyThe purpose of this study was to
investigate student performance on the AIMS assessment for ELL and non-ELL students. The study was designed to determine student performance differences on the AIMS Math and Reading assessments between ELL and non-ELL students across grade and time.
Research Questions1. Are there significant differences in AIMS
performance (Reading and Math) for students across the levels of ELL status?
Research Questions1. Are there significant differences in AIMS
performance (Reading and Math) for students across the levels of ELL status?
2. Does longitudinal performance on the AIMS exam differ significantly for students classified as proficient compared to students classified as ELL?
Sample• From a large Arizona K-8 school district
– District population – approximately 5000 students/year• Predominantly Hispanic (over 99% in
current sample)• 96% Second language learners at
admission• 9 Schools; one pre, six K-6th, and two 7-
8th
• All Title 1 – approximately 100% students on free/reduced lunch
Sample• From a large Arizona K-8 school district• Sample consisted of:
– 3rd, 4th, 5th, and 6th graders– Data from years 2008, 2009, and 2010– Must have completed Math or Reading AIMS – All Hispanic (Less than 1 % of available sample
was non-Hispanic, therefore dropped from analyses)
– 90% on free-reduced lunch at the time of the study
– Gender approximately 50/50 male/female, no gender comparisons done in this study
Research Design• Ex Post Facto
– Uses existing data– Pre-formed groups (e.g. ELL vs. non-ELL,
grades, etc…)– Compare performance on assessments for
students across time and grade– Used Analyses of Variance to answer each
research question.• Multi-factor Between-Subject design (Q. 1)• Mixed ANOVA, between by within-factor
design (Q.2)

Demographic Information• Sub-Sample for Research Question
2– Assessment data needed to be
complete for all three years– Group of 765 students provided
assessment data for all three years• 375 3rd grades, 390 4th graders• 71.8% classified as ELL in 2008• 51.9% Female, 48.0% Male
Research Question 1Are there significant differences in AIMS
performance (Reading and Math) for students across the levels of ELL status?
• Used a series of Between-subject ANOVAs–Between-subject factors: Grade and ELL status–Separate analyses for Math and Reading–Separate analyses for each year of data, 2008, 2009, and 2010–Outcome is category of performance on assessment

Research Question 1• Findings were consistent across year of data,
therefore will present 2008 information as an example
• Math analyses:– No interactions between grade and ELL status– Significant main effect of ELL status and grade– Large effect of ELL status
• Reading Analyses:– Significant interactions between grade and ELL status– Some very minor difference between year, overall result that
grade 5 performance different for ELL and non-ELL students relative to other grades.
– Large effect sizes and differences between ELL and non-ELL students

Conclusion for Research Question 1
• Overall better performance for non-ELL students than ELL students– Largest Effect Size for ELL status – 20-24% of
variance– Consistent across Math and Reading– Consistent across year of data
• Performance on Math better than performance on Reading
• Transitioning students may attenuate the non-ELL student performance at higher grades, i.e. all students are improving at a higher rate, but time since transitioning to proficient may be better index than grade
Research Question 2Does longitudinal performance on the AIMS exam
differ significantly for students classified as proficient compared to students classified as ELL?

Research Question 2• Math analyses:
– No interactions between ELL status and Year– Significant main effect of ELL status and grade– Large effect of ELL status (.185)– Small effect of Year (.023)
• Reading Analyses:– Significant interactions between ELL status and Year (ES
= .020)– Large Effect for ELL status (.227)– Small Effect of Year (.044)– No real change across time for non-ELL students, but changes
across time for ELL students

Conclusion for Research Question 2
•Similar results for Math and Reading results for differences in ELL and non-ELL student performance gap
–Large effect of ELL status–Smaller effect of year
•Not a large amount of growth across time in Math and Reading
–Possible attenuation from transitioning students
•Clear growth in reading across year for ELL students, not for non-ELL students
Future Research
1. Investigate individual level changes in AIMS performance for ELL and non-ELL students.• Allows for control of variables at an
individual level• Acculturation• Transition points for AZELLA• Socio-economic• Academic achievement (grades)• Mobility (moving between schools)• Ethnicity• Gender
Future Research
2. Compare ELL and non-ELL students across multiple states and multiple ELL populations.• Extend findings to other
languages/ethnicities• Investigate curriculum and ELL
program differences across multiple districts and multiple states to improve understanding of the role of curriculum, ELL programs, and the assessments themselves.
Future Research
3. Investigate and include appropriate measures of acculturation, as well as language• Acculturation vs. Language• Determine the relationship between
changes in acculturation across time• If acculturation accounts for differences
between ELL and non-ELL students on assessment, can help identify ethnic bias.
