The post-doctoral trainee on our T32 award was paid the correct amount of stipend but was paid out of object code 01-20, not 01-50. Is this allowable?

No. Per NIH and UW policy, trainees must be paid the correct stipend amount and the stipend must be paid from the correct object code. Object code 01-20 is reserved for Auxiliary Teaching Staff Salaries only; payment under this object code indicates an employer-employee relationship, which is not allowable on T32 awards. If a trainee is not paid under the correct object code (01-50 for post-docs; 01-90 for pre-docs), the trainee will receive fringe benefits that are unallowable under NIH policy. Please see PAFC’s additional guidance on T32 Training Grants for more information.
