I intend to send my CV for a position and on the recruitment note was written that candidates who have a good knowledge of the English language are going to receive priority on the selection process.
I have a score of 643 on the TOEFL ITP test (Test of English as a Foreign Language), which indicates that I am on proficiency level. The problem is that "ITP tests are administered by an institution and for internal use" and I do not know if I am allowed to inform my test score (e.g. write it on my CV) to another institution.
I have not made another type of language test; therefore, I do not have a certification of proficiency (one like the TOEFL iBT would give me, because it is recognized by a large number of places, instead of being "valid" only for the institution that administered it).
If I do not include my TOEFL ITP score in the CV that I intend to send, do you think that I still may describe that I have a good knowledge of English? Is it a good idea to claim this without describing inside the CV that there is an evidence for it? Is it better to include my ITP test score than to occult it until asked for evidence?
