John K. Kraybill is an ALJ at the Oak Brook office. With a lifetime approval rate of 56% over 3,121 decisions, his record sits slightly below the national average of 58%. Because case assignment is random, understanding your judge's history is a vital part of your preparation. Aggregate rates describe past decisions, not predictions for individual hearings; an attorney can help you prepare for this judge's specific bench.
This page presents publicly available SSA Office of Hearings Operations disposition data, with no editorial rating or evaluation. ALJs are independent decisionmakers; aggregate statistics describe past patterns, not predictions of how any individual case will be decided. Information here is provided for hearing preparation, not as legal advice.
Approval rates
Comparing a judge's performance to broader benchmarks provides context for your upcoming hearing. Judge Kraybill’s 56% lifetime approval rate is measured against the Oak Brook office's latest rate of 57% and the national average of 58%. These figures are derived from a significant docket of 3,121 decisions, offering a reliable look at historical trends. Aggregate rates describe past decisions, not predictions for your individual hearing.
Office- and national-level breakdowns of fully favorable vs denial rates aren't currently published by SSA in the per-office disposition data. The judge's own breakdown is the detail we have today.
Approval rate over time
Year-over-year approval rate across Judge Kraybill's docket. Annual rates fluctuate with the mix of cases SSA assigns; the longer-run pattern is more informative than any single year.
Decision pattern
Over a two-year tenure, the approval pattern for Judge Kraybill has shown a shift from 58% in 2016 to 50% in 2017. This trend reflects a change in the volume of decisions, moving from 2,704 in the initial period to 954 in the subsequent year. Such variations are common and often result from shifts in the complexity of cases or the specific evidence presented. This pattern suggests a transition in the judge's recent caseload dynamics.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Kraybill's bench. Judge-specific preparation guidance requires a corpus of public Appeals Council decisions involving each judge, which we haven't built yet.
- Bring a clean treating-physician record. Longitudinal primary-care or specialist notes spanning the disability period, with consistent symptom documentation, are typically the strongest evidence at hearing. A single month's records usually aren't enough.
- Don't rely on consultative exams alone. If your medical evidence is built primarily around a one-time CE finding, expect detailed questioning. Supplement with treating-source statements where possible.
- Prepare for daily-activity questions. Have honest, specific answers about a typical day. Answers that conflict with the medical record (in either direction) tend to hurt credibility.
- Expect transferable-skills probing. A vocational expert will usually testify about jobs available to someone with your limitations. Your representative should be prepared to cross-examine.
