    Create a function that analyzes student assessment data to identify learners who have demonstrated mastery by meeting or exceeding a specified performance threshold. The function should accept a dictionary containing student names and their corresponding assessment scores, along with a minimum score requirement, and return a filtered list of students who qualify for advanced learning materials. The resulting dictionary should maintain only those students whose scores meet or exceed the specified threshold value.
