The Government Accountability Office is set to release Tuesday the results of its long-awaited review into the Federal Reserve's "stress tests," annual health checkups for the biggest U.S. banks.

GAO spokesman Charles Young said the office's report on the stress tests was scheduled to be released Tuesday around 11 a.m. EST. The review began around January 2015, but once complete such reports by the independent agency must go through quality assurance procedures.

The review followed a September 2014 request by House Financial Services Committee Chairman Rep. Jeb Hensarling (R., Texas) to "better understand the costs, benefits and effectiveness" of the stress tests and other Fed banking oversight activities, according to a copy of a letter he wrote May 26 to Fed Chairwoman Janet Yellen.

Mr. Hensarling also expressed concern in that letter about how the Fed was carrying out the tests, and a perceived lack of transparency by the central bank when conducting its assessments.

The GAO report, which runs to around 100 pages, has at least 15 recommendations in it, including one about opportunities to enhance transparency and disclosures, according to a person briefed on its contents.

Its scope also focuses on how the Fed's various stress tests and risk models compare, and its qualitative assessments of a bank's financial health. Specifically, the GAO addressed how the Fed designed its hypothetical scenarios for stress testing the regulated institutions, and examines the Fed's modeling procedures for deficiencies, the person added.

Eric Kollig, a spokesman for the Federal Reserve, had no comment on the stress test review process.
