Grounded in Cummins&rsquo; Interdependence Hypothesis, the study draws mainly on semi-structured teacher interviews to examine reported links between Persian proficiency, classroom comprehension, literacy transfer, learner confidence, and English learning difficulties. The findings suggest that, from teachers&rsquo; perspectives, Persian functions as an important instructional bridge through which students access English explanations, grammatical terminology, and literacy practices. However, the study does not establish direct causal effects. Rather, it identifies teacher-reported patterns indicating that weaker Persian proficiency may be associated with reduced access to English instruction, lower participation, and greater emotional difficulty in English classes. The findings point to the need for early Persian literacy support, balanced multilingual pedagogy, and careful use of Balochi as a supplementary scaffold in bilingual classrooms.</span></span></span></span><br> &nbsp; Balochi-Persian bilingual students, classroom comprehension, English Learning, Persian Proficiency 0 0 http://cals.gonbad.ac.ir/browse.php?a_code=A-10-29-2&slc_lang=en&sid=1 Farideh Okati farideh.okati@uoz.ac.ir 1003194753284600615 1003194753284600615 Yes English Dept., Faculty of Literatur, Univ. of Zabol, Zabol, Irane Vahid Ghafrooi vahid.ghafrooi@gmail.com 1003194753284600616 1003194753284600616 No English Dept., University of Zabol, Zabol, Iran
