August 2017—Quantum theory is often interpreted to mean an object can be in two places simultaneously. Unfortunately, quantum theory doesn’t apply to laboratory directors, at least not on a scheduling level. Like the rest of us, directors can be in only one place at a time, no matter how many laboratories they oversee. Now a change to the CAP Laboratory Accreditation Program’s checklists will clarify expectations for directors who are in charge of more than one laboratory. The 2017 edition of the checklists, released this month, has eliminated the specific requirements for laboratory directors who are not on site full time and has clarified responsibilities for all directors, on site or remote.
