Mark Triplett has a lifetime approval rate of 42% across 20,422 decisions, which is below the national average of 58%. While recent periods show variance, these aggregate rates describe past decisions rather than predictions for your specific hearing. Because case assignment is random, understanding your judge's history is a vital step in preparing your evidence. An attorney can help you prepare for the specific requirements of this judge's courtroom.
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 approval rate to broader benchmarks provides context for the hearing process. Judge Triplett has issued 20,422 lifetime decisions, establishing a significant statistical record. While his latest approval rate of 50% is 16 points below the national average, this figure is based on a specific period of activity. 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 Triplett'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 Triplett has seen fluctuations in his annual approval rates. After a period of lower approval percentages between 2017 and 2021, the data shows a shift toward higher approval rates in 2023 and 2025. This variation suggests that the judge's decision-making pattern is responsive to changes in case evidence or legal standards over time. The latest period reflects a continuation of this recent trend toward higher approval outcomes.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Triplett'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.
