's parenting coach, Lisa Hacker, testified at Friday's hearing, a newly released court document revealed Tuesday.
The document shows that Hacker was sworn in and testified in person, and her report was also submitted into evidence.
Asked whether the report was critical of Spears, her attorney Sorrell Trope replied: "There were some negative things, and some positive, but the beneficial things far outweighed the negative."
The document also shows that on Oct. 25 and 26, Spears's attorneys filed two last-minute requests to the court seeking "modification to drug testing," but no details were given. The singer is currently subjected to twice-weekly random tests for drugs and alcohol.
The newly released papers contain scant detail. The commissioner's complete ruling is expected later Tuesday.
Spears and her ex-husband, Kevin Federline
, are currently undergoing co-parenting counseling and classes together. Their next hearing is Nov. 26.
Trope tells PEOPLE that he remains "absolutely confident that Ms. Spears will eventually regain 50-50 custody."
Currently, Federline retains physical custody of their children, Preston, 2, and Jayden James, 1, while Spears has monitored visitation rights.
