Approval rate over time
Year-over-year approval rate across Judge Mason Jr.'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 his 10 years on the bench, Judge Mason has shown a varied approval trend, peaking at 71% in 2024 before reaching 60% in 2025. His lifetime average of 62% suggests a consistent approach to evaluating evidence, despite year-to-year fluctuations. The recent period reflects a return toward his long-term average. While his baseline is steady, the specific evidence and case mix you present remain the primary drivers of your individual outcome.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mason Jr.'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.
