Why is it important for principals to hire experienced teachers? Let me count the ways.
First, it's important for a teacher to have a deep knowledge of the curriculum he or she is teaching. Without this understanding of the topic, the teacher can only scratch the surface and make it more difficult for the students to succeed academically, especially with "Common Core" being implemented in the schools.
Second, An experienced teacher has a track record and any Principal who cares to investigate the teacher's ability in the classroom can easily do so and decide if that teacher is appropriate for their school. Inexperienced and "newbie teachers" do not have such a track record and when a Principal hires an inexperienced teacher for their school it's a "crap-shoot" to say the least and a good 50% of the time it will be "snake eyes" with th students losing...
Third, the most difficult part of teaching is "classroom management" and it takes years for inexperienced teachers to master the skills necessary to maintain discipline in the classroom. On the other hand, experienced teachers have "been their and done that" and are usually proficient in the difficult art of "classroom management".
Fourth, no Principal wants their students to become "guinea pigs" as the inexperienced teacher struggles through an unfamiliar curriculum and try to maintain classroom discipline at the same time. This steep learning curve for the teacher puts the students at a disadvantage academically to their peers who are fortunate to have an experienced teacher. However, many principals do just that by hiring the inexperienced teacher, usually becuse of their school's budget.
Finally, an experienced teacher brings maturity and stability to the school and their experience can be used to mentor the inexperienced teacher in the many complicated skills it takes to run a classroom.
