Approval rates

Comparing approval rates requires looking at data from the same timeframe to ensure accuracy. While your judge's overall approval rate since 2017 is 65%, recent reporting periods show different trends compared to the office, state, and national averages. The 2,971 decisions on record provide a sample size for understanding this judge's historical pattern.

Decision pattern

The approval rate for Ruy V. Diaz has shifted since 2017. The latest reporting period shows an 86% approval rate, which sits 14 percentage points above the office and state averages of 72%. This recent performance reflects a trend that may be influenced by the specific mix of cases assigned to your judge.

Preparing for an SSDI hearing

The guidance below applies to any SSDI hearing, not specifically to Judge Diaz'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.
