Decision pattern
The approval rate for Susan F. Zapf has remained relatively steady throughout the period from January 2016 to September 2021. With 2,300 decisions on record, the data shows annual fluctuations, such as a low of 46% in 2016 and 2018, and a high of 51% in 2017 and 2020.

Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Zapf'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.
