The answer depends on the applying organization and how much work needs to be completed before submitting. It is hard to predict how long it will take an applicant to complete the application. The Standards for Excellence Institute is available to help nonprofits set goals, and to answer questions throughout the application journey. Once submitted, the review process will start when the application fee is paid. For Basics applicants, the review process usually takes 4-6 weeks. For full accreditation the review process on average takes 4-6 months as each application goes through three reviews and there may be clarifying questions the organization needs to answer after each review.
