According to POSIX priority value returned from pthread_getschedparam() shall be the value specified by the most recent pthread_setschedparam(), pthread_setschedprio(), or pthread_create() call affecting the target thread. Read this as though a temporary lower priority due to the sporadic server policy shall not be visible through pthread_getschedparam(). Thus, use rtems_task_set_priority() to get the current priority of the threads. Use a priority ceiling mutex to prevent sporadic server priority adjustments.
