What is the CPS Opportunity Index?
The CPS Opportunity Index is a tool that uses school, community, and historical factors to measure differences in access to opportunity across schools in the district. It helps ensure that schools with high levels of need get the resources they require to have strong and healthy school communities. CPS Offices, Networks, and External Partners can use the Opportunity Index when deciding how to distribute resources.
CPS Opportunity Index Individual School Scores
Opportunity Index Sum Score: The sum of each of the indicator scores. Schools range from 12 (lowest need) to 48 (highest need) out of a possible 55 points.
Resource equity at CPS
At CPS, we are committed to Equity. We use an Equity Lens in all our work to understand the structure and conditions that create and sustain systemic inequities. This helps us make the necessary changes to build more equitable learning environments where all students can achieve their full potential. In alignment with the CPS Strategic Plan, “Success 2019: Together We Rise,” and the CPS Equity Framework, the Opportunity Index (OI) is a tool to help achieve Resource Equity. Resource Equity means consistently giving priority and resources such as staff, time, and money, based on the different levels of need and opportunity across our schools. The Opportunity Index operates on the principle of Targeted Universalism. This means that different groups might need specific support to achieve the same goals.
The Opportunity Index is based on many years of research about how school districts can consider systemic oppression and distribute resources to equitably support all students. Experts in child development understand that a child’s well-being is affected by their immediate surroundings (like school), which exist in larger community and historical factors that shape policies, opportunities, and social norms.
Developing and updating the
Opportunity Index
The CPS Opportunity Index was created by working with CPS staff, community members, and research partners to make sure their opinions and needs were central to the process. The Office of Equity is committed to continuously improving the Opportunity Index, and used Inclusive Partnerships, which is a key part of the CPS Equity Framework, to revise the previous version (the SY24 Opportunity Index). This was accomplished with the SY25 Opportunity Index Working Group (OIWG), which led to the development of the SY25 Opportunity Index. To learn more about the process of updating the Opportunity Index, please review the SY25 OIWG Phase 1 Summary. This revision process made sure to include the input of different people, including those with long-term experience with the Opportunity Index, those affected by decisions around the Opportunity Index, and those responsible for using the Opportunity Index.

School Demographics
These indicators reflect the characteristics of the students attending the school.
- % of Students with Disabilities: The percentage of all enrolled students with an assigned Individualized Education Program (IEP)
- % of English Learner Students: The percentage of all enrolled students designated as English Learners
- % of Students in Temporary Living Situations (STLS): The percentage of all enrolled students who are designated as STLS
- % of Teachers Retained: The percentage of staff employed in the previous school year who are still with the school in the current school year
- Simpson Diversity Index: This index measures the likelihood that two randomly selected students will be of the same race (how not diverse a school is)
Community Factors
These indicators reflect the socioeconomic environment in which the attending students live.
- 200% Poverty Rate: A weighted 200% poverty rate (family income within 200% of the federal poverty line) based on students’ residing census tract
- % Uninsured: A weighted percentage of uninsured individuals based on students' residing census tract
- Chicago Hardship Index: Weighted Chicago Community Area Hardship Index (2018-2022) based on students’ residing community area
- Community Life Expectancy: Weighted average community life expectancy based on students’ residing community area
For all community factors, all students enrolled in CPS on the 20th day of the school year are connected to a census tract and a community area based on the home address they provide through a process called geocoding. This helps accurately link student data and community data based on where students actually live, not just where the school they attend is located.
Historical School Funding
These indicators account for the resources schools have experienced in previous years.
- School Budget and Changes in School Budget: An average of two components: (a) Percentile of the average total budget from 2014 - 2024, and (b) Percentile of the average percentage change in budget from 2014-2024
- Capital and Outside Funding: The total amount of Capital and Outside funds (Tax Increment Funding (TIF) funds, state funding, and other outside sources (e.g., Friends of Dollars) as they become identified) received between 2008-2023
How the Opportunity Index should
(and should not) be used
Methodology
The CPS Opportunity Index scores are calculated for traditional elementary and high schools, both those managed by the district and charter schools. Some types of schools, including Options, Safe, Early Learning Centers, and Specialty, are not given Opportunity Index scores because their structures and resourcing are different from traditional schools. The data for the CPS Opportunity Index will be updated once a year.
Each indicator’s data is divided into five equal groups called quintiles, with each quintile representing 20% of the values. This helps compare data with different ranges. Each quintile corresponds to a score between 1 and 5 depending on proximity to opportunity and level of need. An indicator score of 1 means closer access to opportunity/lowest need and 5 means furthest from access to opportunity/highest need. Quintiles are calculated separately for elementary and high schools. Charter schools’ indicator scores are calculated based on the quintiles identified from district-managed schools’ data.
A school’s Opportunity Index score can either be calculated as the average or the sum of their 11 indicator scores. Both the average and sum scores are mathematically equivalent. The Office of Equity suggests that stakeholders use the average score which calculates the final score for each school between 1 (closest to opportunity/lowest need) and 5 (furthest from opportunity/highest need).
The sum score is used in certain cases such as the CPS School Budget formula.
