A three-page document released Tuesday by the Los Angeles court system shows that Lohan, 23, is in good standing with her DUI class, despite reports that she's almost certainly facing jail time at a hearing Thursday for alleged poor attendance.
"The judge is concerned about Lindsay's alleged excessive partying but that doesn't necessarily mean she's facing jail time," says a source close to the case. "But it's all up to the judge at the hearing if Lohan's in violation [of her probation] or not. There might be new conditions placed on her."
An attorney for Lohan, who has been in France this week at the Cannes Film Festival, didn't immediately respond to calls for comment. On Monday, L.A. Superior Court Judge Marsha Revel ordered Lohan to personally show this Thursday.
The progress report also says the actress "attends regularly and consistently communicates in a timely manner to reschedule [her classes]" and that "her attitude is positive and receptive to ideas regarding lifestyle changes."
The report does say, however, that when Lohan first transferred into the program in March 2009, she "struggled with consistency and punctuality in attending her scheduled activities."
As of May 4, Lohan's attended 17 of 26 Alcoholics Anonymous meetings, 19 of 26 group sessions, 24 of 26 interview sessions, and completed all six alcohol education classes.
The actress's mother, Dina Lohan, praised the report's positive and encouraging tone, telling PEOPLE that Right On Programs, the alcohol education program that drafted the report, has been a positive influence on Lindsay's turbulent life. "They're amazing people and it's wonderful, helpful program," she said.
