A student instructor does all of the regular duties that a teacher does, except that they are still a student themselves. Most student instructors are gaining professional experience in order to become full-time teachers or instructors.
Student instructors can work with any age group and specialize in any subject. Just like regular instructors, they plan lessons, lecture students on important topics, and grade assignments. They make sure that students are engaging with material by including interactive elements into their lessons, like discussions or lab experiments. Student instructors need to have excellent public speaking skills, classroom management skills, and strong organizational skills in order to handle the vast amounts of grading they need to do.
By definition, student instructors are still in school themselves. Most are working towards a bachelor's or master's degree in education. Since this is a training position, they don't need much prior experience but some experience working with children or young people is helpful. Student instructors earn an average annual salary of $55,232, although some student teaching positions are unpaid.
