Overview History Rationale Referral-to-Eligibility Ratio Preliminary Data Challenges in Assessing the

Referral Process

The Indiana Disproportionality Project (IDP) Collaboration of IDOE and Center for

Evaluation and Education Policy at Indiana University Document status of minority

disproportionality in Indiana Use that information to guide change

planning

Project History and Timeline Phase I (1999-2000):

Developing Measures of Disproportionality Phase II (2000-2001):

Understanding What Contributes to Special Ed. Disproportionality

Phase III (2002-Present): Addressing Disproportionality in Local

School Corporations and Addressing Key Research Questions

Findings: Years One and Two Statewide: African American most

severe Mild Mental Disability 3.29 x more Emotional Disturbance 2.38 x more Moderate MD 1.91 x more Communication Disorder 35% less Learning Disabled 6% less

AA underrepresented in LRE Disproportionality not uniformly

distributed

Beyond the Numbers: Where Does It Come From and What Should We Do?To remediate we first have to

understand Literature review of causes – e.g.

National Research Council, Harvard Civil Rights Project

IDP Qualitative Study LEAD Projects in ten corporations

How Do We Measure Progress? Conversation in district

How do we monitor progress? The problem of short term change in

disproportionality.

Solution: Examine representation at various points in the decision-making process

Exploration of Referral to Eligibility

Rationale

The Contribution of the Special Ed. Process NRC (2002) unable to draw firm conclusion High percentage of students referred are

placed (Algozzine, Ysseldyke, & Christensen, 1983)

Referral most important judgment made in assigning students to disability programs (Ysseldyke & Algozzine, 1983)

Teachers quickly form inaccurate impressions, especially of black males (Irvine, 1990)

The Referral-to-

Eligibility Ratio

Referral-to-Eligibility Ratio (RER)

Referral for Assistance Referral to General Education

Intervention Referral to Psychoeducational

Assessment Special Education Placement

Questions to be Addressed Where in the referral to eligibility

process is disproportionality occurring?

How do we know we are making a difference in disproportionality?

Are our specific general education interventions working?

Data Tracking Process Collecting data from administrators

directly working with pre-referral intervention teams or from central office personnel on Excel form

Data at 4 points in the special education decision making process

Analysis of students within and across these stages

How Do We Know there is Disproportionality?

Composition Index Indicates the representation of a group at a particular stage Example: 100 students are referred for assistance and 25

are Hispanic, the composition is 25% Risk Index

Indicates the risk of a group being represented at a particular stage

Example: 100 African American students attend a school and 10 are assessed for services, risk would be 10%

Relative Risk The ratio of risk for one group compared to all other groups Example: Risk of assessment for African Americans is 10%

and all other students is 5%, then the relative risk for African Americans is 2.0

Calculation Considerations Risk relative to all other students

or one group of students (e.g., white)

Numbers contingent on previous step, or population as a whole

Look at all students going through process, or just initial referrals, re-evaluations, etc.

School District Example

Sample District: King Community School Corporation Diverse, Urban District Wide Use of Pre-Referral

Intervention Form varies widely among schools

Follow students through this sample district to understand the calculations and process

General Conclusions

Within the Process Compare contribution of each stage

to representation of group Compare one group’s

representation at specific stage to representation of other groups

Investigate different outcomes Assessment hit rate, Process

outcomes, Incidence rate

Schools & District Comparisons Which schools are contributing to

over/under representation? How do the schools’ numbers

compare to the district as a whole? How does the process differ across

schools? Leads to questions about the

contextual factors not necessary captured in data form

Challenges in Assessing the

Referral Process

Issues Encountered Calculations based on Small

Numbers

Nature of the Beast

Logistical Challenges

Approaches to Addressing Challenges LEAD Project: Culture

Competence

Technical support

Build in-house systems and ownership
