APTIS is the best choice if you are wanting to demonstrate the Conselleria de Educación of the local government that you have the required level of English to teach in the Baleares.
If you are wanting to teach outside of the Baleraes then we strongly recommend that you do the FCE or other recognised exams of Cambridge or TOEFL as the APTIS is a relatively new exam and it is not completely recognised by the multinational companies throughout the world as the Cambridge exams or the TOEFL.
