Generally how accurate is VOR course alignment?

VOR course alignment accuracy refers to how closely the azimuth information from a VOR matches the published radial from the station. Under normal operating conditions with proper maintenance, the system is designed to indicate a course within about one degree of the true radial. That level of precision supports reliable IFR navigation over typical distances. Tighter tolerances like a half degree or a quarter degree are beyond what a VOR is guaranteed to provide, while a two-degree tolerance would be too loose for dependable tracking. In practice, pilots may cross-check VOR guidance with other sources when precision is critical or reception is degraded, but the standard expectation is roughly plus or minus one degree.
