Whether it's necessary to bring a checklist of required materials for a meeting depends on several factors:

• Your Role: If you are the meeting organizer, providing a checklist of materials for attendees is a good practice to ensure everyone is prepared.
• Meeting Complexity: For complex meetings involving multiple documents or specific tools, a checklist is highly beneficial.
• Attendee Familiarity: If attendees are new or unfamiliar with the meeting's content or required items, a checklist can be very helpful.
• Past Experiences: If previous meetings suffered from attendees forgetting necessary materials, a checklist can prevent recurrence.

In summary, while not always strictly necessary, providing a checklist is generally a good practice that promotes preparedness and efficiency. If you are an attendee, it's always wise to confirm what materials are expected.
