    In an adaptive learning system that uses palindromic numbers as milestone markers, develop a function that determines the next achievement milestone by finding the smallest palindromic number greater than a student's current score. The system uses these palindromic checkpoints to create recognizable progress markers for students, and your function must return this next milestone as an integer value.
