Which of the following is a common requirement for probation?

Regular check-ins with a probation officer or a court are a standard requirement for individuals on probation. This requirement serves several important functions within the probation process. First, it allows the probation officer to monitor compliance with the terms of probation, ensure that the individual is adhering to any restrictions or requirements, and provide support as needed. Regular check-ins also help maintain accountability, as the individual must report their progress and adherence to the conditions set out by the court.

The other options presented do not reflect common requirements for probation. Mandatory attendance at every court hearing is not typical, as not all cases require the individual to appear regularly in court after their sentencing. Immediate financial restitution to all victims can be ordered, but it's not universally required for everyone on probation, as the conditions of probation vary widely based on the individual case and the judge's discretion. Furthermore, a permanent ban from any form of employment would be seen as overly punitive and is not a standard component of probation in Illinois or generally. Instead, probation often encourages individuals to maintain employment, as stability can be a significant factor in successful rehabilitation.
