The knowledge of the English language is fundamental for the application of evidence-based practice. Hence, this study explores, through an online survey, the (1) perceived and (2) actual level of Scientific English among Italian undergraduate (UGs) and postgraduate (PGs) physiotherapists. As for (1), the participants expressed their agreement with 10 statements regarding the attitude towards Scientific English through a 1–4 Likert-type scale, with consensus set at ≥70%. As for (2), an ad-hoc 10-point questionnaire was developed through a Delphi procedure, with a pass score set at ≥60%. The survey was completed by 421 participants (UG: 47%; PG: 53%). As for (1), consensus was achieved in both groups in 4 out of 10 statements, specifically the ones addressing the capability to fully understand a scientific paper and physiotherapy-specific language in English. As for (2), the mean score reached by both groups was below 60%. The participants who had studied or were studying at a university in southern Italy presented 2.56 [1.54; 4.24] times higher odds to fail the test. New strategies to bridge the gap in the knowledge of Scientific English in Italy should be developed, through the creation of a unique syllabus tailored to the needs of future physiotherapists.
