Same here, I know there are lots of studies out there about testing and teacher effectiveness, but it will be interesting to see what happens when the report is published.
I work in a school district (nowhere near California, let alone LA) and have to say that there are lots of variables. We have a large group of English Language Learners, a large number of kids with 'special needs' (because being full of energy when you're 8 years old is apparently a disease now) and now there are so many consult minutes that students are occupied with a lot of other distractions that take them out of their primary classroom and away from their classmates. Some of that may be useful, some of it definitely is not.
I think if we make it easier to fire teachers, it should be easier to hire teachers. There are lots of good teachers (that is, people who CAN teach but do not work as Teachers) out there who simply don't want to jump through the hoops of most modern teacher certification and licensing. And the fact that you are practically forced to pursue a masters degree is a joke, as there are a number of studies that show that having an advanced degree does not make you a better teacher. Instead of wasting a teacher's time with "professional development" that is mandatory and therefore not interesting to the teachers, they come to resent the process. Instead they should place more reward on teachers who go the extra mile and who can't go a day without coming up with some way to engage their students or to tweak a lesson plan (the ones who actually like learning and teaching).
A couple other quick ideas:
-Have kids(elementary age) "keep" their teacher from year to year. Having to make and break that strong teacher/student connection each school year, especially at young ages has a lot to do with that 'summer drop off' that students experience. Teachers should be able to instruct from grades 1-5.
- Shorter summer vacation. I'm not an ogre, you can have a nice 3 or 4 week break, but I would much rather take some of those extra days and make them vacations elsewhere in the calendar- or give them to the parents of the students to use in line with their own vacation time. Yes that means teachers will maybe teach to a room half-empty, but in my school district parents tend to take their kids regardless and it may cut down on unapproved absences.
