How long must the Maryland Tree Expert keep records?

• A. 1 year
• B. 3 years
• C. 5 years
• D. 10 years

Answer: (B)

Record retention duration is what this item tests. For Maryland Tree Experts, the requirement is to keep records for three years. This time frame provides a reliable window for audits, client inquiries, or any questions that arise about past work. Maintaining documentation—dates and locations of jobs, materials and pesticides used, treatment methods, warnings given, and client approvals—ensures you can verify exactly what was done and when. It also supports accountability and compliance with regulatory oversight, while avoiding the burden of storing records much longer than necessary. A shorter period, like one year, might leave you without needed documentation if issues are raised later, whereas longer periods, such as five or ten years, aren’t required by the rule. So, three years is the appropriate and expected retention period.
