If your approved study involves MTurk, you need to plan for its discontinuation. Steps you should take include: 

• Notify participants: If participants are owed payment or are mid-study, create a plan to communicate the closure to ensure they receive outstanding compensation.
• Submit a modification: If MTurk is named in your protocol and is the only platform approved to recruit, collect data, and pay participants, you will need to submit a modification to:
• Update your protocol, recruitment materials, consent form, and related study documents to remove MTurk references
• Describe how you will communicate the closure to current participants, and provide a copy of the notification
• Propose a new recruitment/data collection method such as Prolific or similar

Note: You do not need to submit a modification if:

• You have already finished all study activities, including MTurk payments; or
• Your approved protocol already includes other recruitment, data collection, or payment platforms in addition to MTurk.
