The JCMT BISTRO survey (B-Fields in STar-forming RegiOns) is a large-scale polarimetric program using SCUBA-2/POL-2 to systematically map magnetic field structures across a wide range of star-forming environments. In this talk, I will present an overview of the survey and highlight recent results spanning scales from molecular clouds to dense cores, revealing diverse magnetic field morphologies from ordered large-scale fields to complex structures in clustered regions. By combining polarization data with spectroscopic observations, we apply techniques such as the Davis–Chandrasekhar–Fermi method to estimate magnetic field strengths and assess their dynamical importance. These results provide new insights into the role of magnetic fields in regulating mass accretion, fragmentation, and disk formation, and represent an important step toward a unified, multi-scale understanding of star formation.
