Agree with Whopity, although it would depend on what the examiners handbook and/or standards documents are for where you operate.
In the UK, during the airwork section both navigation and ATC liason are the responsibility of the examiner. Now within that an examiner might nominate a specific area that he wants the candidate to operate in, including remaining in the appropriate class of airspace, in which case two things:
First it must be absolutely clear in the brief what is expected.
Second having told the candidate what is expected you have to let him get on with it and if at any time you have to intervene then fair enough, he's blobbed it.
If though the brief was simply that during the airwork section, navigation and ATC liason were the examiner's responsibility and he subsequrntly asks for a climb to ... on a heading of ..., then I would see the avoiding of controlled airspace or obtaing an appropriate clearance to enter it as his responsibility.
During the departure, en-foute and arrival sections then clearly the navigation and ATC are all the candidates responsibility, but at no point during these sections would the examiner start issuing climb or heading instructions.
