For me it got better . I remember when i was in second grade i used to stutter while saying anything. this one time i was speaking to my teacher and all i could speak was si..r...mer..s...ir and he laughed at me then mocked me then all my classmates laughed. That was one of the worst moment of my life . I mean My classmates used to make fun of me all the time but to think my teacher will do something like that. But now i can speak to teachers freely most of the people don't even know that i stutter. I only have problem while saying my name. I think what changed was that i used to get anxious while speaking to people who are older then me and but now that i am 22 years old i can speak to people my age and who are younger then me fluently. It's the older ones that cause me problem.
