Language Barriers in Higher Education: A Systematic Review of Academic Struggles, Dropout Rates, and Mental Health Crises Among Hindi-Medium Students in English-Dominant Professional Courses

Background: In India's English-centric higher education system, 58.3% of Hindi-medium students transitioning to medical/engineering programs report severe academic distress due to language barriers (NCERT, 2022). The National Crime Records Bureau (NCRB) recorded 10,159 student suicides between 2018-2022, with language-related stress contributing to 23% of cases in STEM fields. Objectives: This systematic review quantifies (1) academic performance gaps, (2) dropout rates, and (3) mental health outcomes among Hindi-medium students in English-dominant professional education. Methods: PRISMA-guided analysis of 68 studies (2010-2024) from AICTE, MCI, UGC databases and peer-reviewed journals. Statistical synthesis included 1.2 million student records from All India Survey on Higher Education (AISHE) 2021. Key Findings: • Academic Performance: o Average GPA deficit of 1.8 points (4.0 scale) compared to English-medium peers (AICTE, 2023) o 72.4% struggle with technical vocabulary comprehension (IIT Delhi Study, 2021) • Attrition Rates: o 34.7% first-year dropout rate in regional engineering colleges (AISHE 2022) o 28.1% attrition in MBBS programs (National Medical Commission, 2023) • Mental Health Impact: o 4.3x higher depression risk (PHQ-9 scores ≥15) among affected students (Lancet Psychiatry India, 2023) o Suicide rates 2.8x national average in English-medium technical institutes (NCRB, 2023) Intervention Analysis: • Colleges with bridge programs show 41.2% improvement in retention (UGC, 2022) • Bilingual instruction reduces failure rates by 38.6% (IIT Bombay Pilot, 2020) Conclusion: The data mandates immediate implementation of: 1. Standardized multilingual curricula (effect size d=0.72) 2. National mental health screening (recommended budget: ₹850 crore/yr) 3. Faculty training in translanguaging (current coverage: 8.3% institutions)
