Here is a cleaner, more fluid version of your statement:
I have been a special education teacher for the past 15 years, dedicated to supporting students in developing their literacy and numeracy skills at their individual levels of ability. I am passionate about helping each child grow in confidence and understanding, and I make it a priority to ensure my students know that everyone learns in different ways. I primarily work with second and third grade students with disabilities, including developmental delays, specific learning disabilities, and autism.
