SNAP Performance Metrics Dashboard

The United States Department of Agriculture (USDA) Food and Nutrition Service (FNS) works to ensure SNAP remains an efficient and effective program. The Iowa Department of Health and Human Services (HHS) partners with USDA FNS for the Quality Control (QC) system for SNAP. The data produced from SNAP QC is available to the public and informs work at both USDA FNS and Iowa HHS.

USDA FNS evaluates states on three performance metrics using SNAP QC data:

  • Payment Error Rate (PER) – Measures how accurately HHS determined SNAP eligibility and benefit amounts for those who participate in SNAP. Payment errors include both overpayments and underpayments of benefits.

  • Application Processing Timeliness (APT) – Measures the timeliness of HHS’s processing of initial SNAP applications.

  • Case and Procedural Error Rate (CAPER) – Assesses the accuracy of HHS’s actions in cases in which applicants wrongly did not receive benefits and measures HHS’s compliance with federal procedures, including the timeliness and accuracy of notices.

This dashboard explores the above metrics for Iowa and provides additional context and analysis.


Payment Error Rate

About the payment error rate (PER)


The payment error rate (PER) measures the accuracy of Iowa HHS’s eligibility and benefit determinations for SNAP. Payment errors include both underpayments and overpayments. Payment errors are the result of inadvertent errors made on the part of a SNAP recipient or state agency. The payment error rate does not represent program fraud.

The payment error rate does not differentiate between the sources of each type of error, but does provide an estimate of both over and underpayments of benefits. In FY 2024, the PER accounts for errors above a $57 threshold.

If a household has been found to have received an overpayment of benefits, even if the source of the error was a state agency, agencies are required to work toward recovering excess benefits from households. Households who are found to have received an underpayment in benefits may be able to recoup them through a process to restore lost benefits with Iowa HHS.


Here’s how Iowa’s payment error rate for SNAP broke down in FY 2024.

In FY 2024, Iowa had an underpayment rate of 0.84% and overpayment rate of 5.30%, for a total payment error rate of 6.14%. This was well below the national average of 10.93%.

Digging Deeper: Background on Iowa’s 2019 fine from USDA re: Payment Error Rates


In 2019, the state of Iowa was issued a $1.8 million fine from USDA for having a payment error rate of 10.0% – which was 3.2% higher than the national average in FY 2018 (6.8%).

Iowa chose to designate 50% of the liability amount toward new investments in approved activities to improve SNAP administration through its Business Process Redesign and designated the remaining 50% of the liability amount as at risk for repayment if an excessive payment error rate occurred in FY 2019. This did occur, and the state paid the liability, when the payment error rate for Iowa in FY 2019 increased to 12.5%—5.1% higher than the national average in FY 2019 (7.4%).

More recently, however, Iowa has shown improvements in reducing its payment error rate. While USDA does not have official payment error rate data for FY 2020 and FY 2021 due to the COVID-19 pandemic, according to a 2022 legislative presentation by HHS3, the payment error rate for SNAP in Iowa fell to 9.4% in FY 2020 and 6.6% in FY 2021.

And in FY 2024, the latest year for which we have official USDA data, Iowa’s payment error rate for SNAP was 6.14%—well below the national average of 10.93%.


How does Iowa’s payment error rate (PER) compare with its neighbors?

Iowa’s payment error rate for FY 2024 was higher (worse) than that of Nebraska, South Dakota, and Wisconsin.

Illinois is the only neighboring state with a payment error rate exceeding the national average of 10.93%.


Application Processing Timeliness (APT)

About the application processing timeliness (APT) rate


The SNAP Application Processing Timeliness (APT) rate measures the timeliness of states’ processing of initial SNAP applications. The Food and Nutrition Act of 2008 entitles all eligible households to SNAP benefits within 30 days of application, or within 7 days, if they are eligible for expedited service.

The Application Processing Timeliness rate measures the percentage of applicants who received their benefits within the time period required by federal law. USDA FNS considers APT rates under 95% to be untimely, and classifies APT rates falling below 90% as very untimely.

In addition to Application Processing Timeliness, states also monitor Recertification Processing Timeliness (RPT) and report the data to USDA FNS. Most Iowans on SNAP have to recertify for benefits every six months. Elderly and disabled individuals need to recertify every 12 months. From the latest available USDA data (January-June 2024), Iowa’s RPT rate was 79.1%.


Here’s how Iowa’s SNAP application processing timeliness rate broke down in FY 2023.

Digging Deeper: Iowa’s Application Processing Timeliness Corrective Action Plan


Iowa has been under a Corrective Action Plan (CAP) with USDA FNS since 2023 in regards to its low SNAP Application Processing Timeliness (APT) rate. A root cause analysis conducted by the Iowa Department of Health and Human Services identified major root cause concerns, including the fact that “eligibility staff lack overall knowledge of timeliness policy.”

While the latest annual QC data available from USDA is for FY2023 (and highlighted in this report), more recent data from USDA FNS for the period of January-June 2024 show Iowa’s APT rate slipped further to an abysmal 63.0% (ranking 44th of all states). It is entirely possible that Iowa’s APT rate for FY 2024 will be even lower than it was in FY 2023.

On the positive side, it does appear that work at Iowa HHS to increase Application Processing Timeliness is starting to show some improvements. The department has moved to a dedicated SNAP team, improved staff processes and training, and its SNAP Leadership Council has expanded its focus beyond addressing payment error rates to also address timeliness and other performance metrics.

While Iowa is showing some positive developments in improving its Application Processing Timeliness rate, far too many Iowans are still waiting for SNAP benefits for a time period longer than what is required by federal law.


In FY 2023, Iowa had an application processing timeliness (APT) rate of 77.7%, well below the USDA acceptable range of 95%, and the lowest APT rate on record for Iowa going back to FY 2003.

How does Iowa’s application processing timeliness (APT) rate compare with its neighbors'?

Iowa’s application processing timeliness (APT) rate for FY 2023 was lower (worse) than any and all of its neighboring states.

While Iowa’s SNAP APT was the lowest since FY 2003, the state’s national APT ranking actually increased slightly from FY 2022.


Case and Procedural Error Rate (CAPER)

The case and procedural error rate (CAPER) assesses cases when a household is denied SNAP benefits or has their benefits terminated or suspended. CAPER reflects both the accuracy of the state agency’s determination and their compliance with federal procedural requirements around the determination.

A graphic representation of "CAPER: Case and Procedural Error Rates" showing four circles. The light green circle on the left has a heading of "Accuracy of Action" with an arrow hitting a target (also both in light green) and a subheading of "Was the decision to deny, terminate, or suspend accurate?". Moving to the right is a dark green circle labeled "Accuracy of Procedures" with a graphic depicting points along a pathway to an end goal. The subheading reads "Were the procedures accurately followed?". Moving again to the right, the third circle is light blue in color, with a graphic showing an opened piece of mail with the heading "Accuracy of Household Notice" and a subheading reading "Was the household notified in a clear and accurate way?". The final circle on the right is dark blue in color with a clock graphic and the heading "Timeliness of Action and Notice." The subheading reads "Was the state's action and notification to the household made in a timely manner?"

Here’s how Iowa’s SNAP case and procedural error rate (CAPER) broke down in FY 2024.

text reading "Iowa's worst CAPER on record (since 2012)" in a red box
text reading "35th lowest CAPER (out of 53)" in a red box

This means that in 45.7% of cases where a household’s SNAP benefits were denied, terminated, or suspended one or more of the following was true:

  • The decision was inaccurate;  
  • The notice provided to the household was inaccurate, unclear, insufficient;
  • The notice provided to the household was not timely; and/or  
  • The procedures followed related to these decisions were inaccurate or not timely.
Digging Deeper: What's Driving Iowa's Case and Procedural Error Rate?


In FY 2022, USDA FNS released additional data that provides more specific state-level information related to the four measurements included in the case and procedural error rate. While we do not have updated Iowa-specific data since then, this helps identify areas that have been problematic in the past.

For instance, in FY 2022, in 11% of cases where a denial was made, the record reason for making the denial was found to be inaccurate. This means that 1 in 10 SNAP cases that were denied should not have been.


Iowa’s CAPER for FY 2024 was the highest (worst) in record in Iowa, dating back to 2012.  It was the first year on record that Iowa's CAPER was higher than the national average.
