Furthermore Vinaya lists exceptional conditions when even monks can blamelessly proclaim attainment to laypeople;

pācittiya 8 "yo pana bhikkhu anupasampannassa uttarimanussadhammaṃ
  āroceyya, bhūtasmiṃ pācittiyaṃ."
Not to announce to a layman a realisation that has been achieved. If a
  bhikkhu announces to a layman or to a sāmaṇera, a realisation
  partaking with a jhāna nature or with a stage of ariyā, and this
  realisation has genuinely been achieved, he commits a pācittiya.
On the other hand, a bhikkhu who makes such a declaration, while
  knowing it to be false, commits the pārājika 4. A bhikkhu must avoid
  making his attainments known, even to other bhikkhus. Apart from four
  exceptions when they can do so, ariyās never unveil their
  realisations:
Under a violent threat. Undergoing an oppressive and virulent lack of
  respect. A t the time of passing away. To reveal it to his preceptor
  or to a fellow bhikkhu who does a similar practice.

There are more examples from commentaries in example in case of Ariyupavadantaraya according to VSM one might inquire about the status of another by asking 'Have you gained a footing in this Dhamma & Discipline to which a bhikkhu answers by informing of the realization of sotapatti fruition, whereafter the other Bhikkhu informs him of reviling a noble person and informing about one's own level of attainment. Or take another case where the daughter's status can be inferred from her speaking of Anathapindika as her younger brother
