Does this mean bringing in business and education people to help participate at the k12 level?
Good luck. A few true stories from 3 different states.
The brother of my wife's best friend had a highly successful career as a store manager, district manager, and regional manager for a large retailer. He was one of the most successful managers in the PacNW, having become a store manager at just 26 years old, and a regional manager at 40. He got sick of the long hours and stepped down, now working as a consultant. During the ramp up time of his consultancy business, he volunteered with the DECA club at his niece's high school, leading them to the national competition every year. He then approached the principal offering as a volunteer to teach a class on sales, merchandising, and leadership. He was told he could not teach a credit class as he did not have a teaching certificate, and that his participation in DECA was sufficient to teach this material.
One of my best friends retired after a 28 year career in the Air Force, retiring as a colonel. When he retired, he got involved at his kid's high school, both as a coach and substitute teacher. For a long time, he has been heavily involved in 4H's Know Your Government. He offered to create a teach course material on leadership, time management, and government. Despite this, the principal refused, saying he lacked the qualifications to be a full time teacher and teach for credit material.
In my own experience, I have been volunteering to teach at my kid's junior high school. My kids attend a private, Catholic school. The principal was eager to have someone join and help teach material. We don't have a Catholic high school, so I reached out to the principal at our local high school offering to teach the same material I've been teaching at the junior high for the last 7 years, and was told I could not teach a for credit class without being a certified teacher.
Related to the above, one more story. A guy I went to undergrad with happened to move to the same area I live. When catching up with him, I asked what brought him back. He had went on to get a PhD in computer science. He had started his own company and recently sold it, and decided to enter semi-retirement. He moved to town to teach at the local community college (turns out his wife is from the area). Before I had talked with him, he reached out the same principal at the high school offering to teach computer classes. He got he same response that he wasn't qualified to teach for credit classes without being certified. We compared notes when I met with him, and he noted, "It is easier to get a job as a professor than as a public school teacher."
People with master's degrees and PhD's being declined opportunities to teach classes in material in which they are experts. While at the same time they have barely knowledgeable teachers covering material. Case in point, my daughter's Algebra II teacher is out the rest of the year for maternity leave. The substitute teacher was a history major and has admitted to struggling to recall this material. The only reason she is doing well in the class is because I am an engineer and had years of math that I still rely upon for my job.
If you really think getting "business and education people to help participate at the k12 level" then we need to open doors for people who offer to volunteer their time to do so. Turning away highly knowledgeable people who are experts in their fields because they aren't "qualified"? It's mind boggling. And I guess they do so because of either some law, some clause in some contract, or just plain ole disdain for those who aren't teachers.
