@ Clark…
For CFA  charter candidates requirements CFAI  says,” when you apply for regular membership, you will attest that your submitted work experience qualifies as acceptable professional work experience as defined by the guidelines shown below.
…….To become a regular member, you must have completed four years (48 months) of qualifying work experience in activities that consist to a majority extent of: ……..
Then it clearly states that
*  At least 50 percent of your work experience must be:
-  Directly involved in the investment decision-making process
-  Engaged in responsibilities and/or producing a work product that informs or adds value to that process
*  Positions must be full-time. Part-time positions do not qualify.
Here it does not say anything about exclusion of Internship Position.
While  by  the same CFAI for CIPM the Professional Experience Requirements are stated as:
“You must be a regular member of the CIPM Association to be eligible for the award of the CIPM designation. To qualify for regular membership in the CIPM Association,………….”
Then it goes on to clearly state:
“Summer, part-time, and internship positions do not qualify.”
Evidently it means for CFA Charter experience requirement there is no exclusion clause for internship as long as it meets other requirements e.g must be full time position, 50% work experience must be as per norms etc. Only restriction is that it should not be part-time while for CIPM it has some restriction  regarding internship too.
Hope it clarifies your doubt. In any case it is advisable to just send an email to the CFAI membership dept. they are pretty prompt in resolving queries.
