Approval rates
Comparing approval rates requires looking at consistent timeframes. While you may note an overall approval rate of 68% since 2016, the latest-period performance shows an 84% approval rate, which sits 29 percentage points above the Seattle office average of 55%. These figures are based on a docket of 3,348 decisions. 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 Mangrum'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
The approval pattern for Timothy Mangrum has shifted across the 3,348 decisions on record since 2016. After experiencing fluctuation in the middle years, the trend moved upward, reaching 84% in the most recent partial fiscal year. This latest-period performance is higher than the long-term average, reflecting a recent shift in case outcomes.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mangrum'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.
