A chastened F.B.I. told a secretive court on Friday that it was increasing training and oversight for officials who work on national security wiretap applications in response to problems uncovered by a scathing inspector general report last month about botched surveillance targeting a former Trump campaign adviser.

In a rare unclassified and public filing before the court that oversees wiretapping under the Foreign Intelligence Surveillance Act, or FISA, the F.B.I. also said it would extend its overhaul to requests for orders permitting it to collect logs of its targets’ communications and other business records — not just wiretaps of the contents of phone calls and emails…

The new filing, which detailed 12 steps, like enhancing checklists for preparing filings, added granular detail. It came in response to an unusual public order last month. Rosemary M. Collyer, then the presiding judge on FISA court, ordered the F.B.I. to propose fixes to its process by Jan. 10 to ensure the problems would not recur.
