The study examined financial modelling for portfolio management, investment analysis and non-interest banking in polytechnic education in Nigeria. The descriptive survey design was adopted, targeting all mathematics, Statistics, and Banking and Finance academics in Plateau state Polytechnic, Jos, and United Polytechnic, Jos. A census of 30 teachers was used, and data were gathered by the use of the ―financial Modelling, Portfolio management and Non-Interest Banking Questionnaire (FMPMNIQ)‖, rated on a four-point Likert scale. Validity was ensured via professional review, and reliability was established using the Cronbach’s Alpha method which yielded a reliability coefficient of 0.81. Data were analyzed via the mean and standard deviation, with a 2.50 benchmark for decision-making. Findings showed that financial modelling techniques are actively applied and effective in improving investment analysis, portfolio management, and risk assessment. but, implementation in non-interest banking is limited by some constrained facts; such as, insufficient technical know-how, lack of Shariacompliant frameworks, and inadequate resources. Based on the findings, the study recommends consistent integration of financial modelling in curricula, regular professional improvement for lecturers, and institutional funding in Sharia-compliant frameworks and relevant resources
