Since we have 50 states, and 50 State Board of Education, there is that diversity. Then there are public school districts that have the benefit of higher property taxes, better funding, better prepared students. When a student gets support in reading, math, educational activities at home. States are finding out how beneficial preschool is so now we have K4 programs that are publicly funded. If a parent is helping over-see a student’s progress and difficulties.
When a student is in with a higher achieving pool of peers, the teaching level can be higher all along through the K - 12 years. Some schools have gifted programs. For a student that doesn’t want to put in the effort in elementary school, will fall behind the achievers in middle school. By high school you have a range of ‘diplomas’. That produces a gap for those that can go on to a 4 year college and do well, and those that may need to go to community college and take pre-college or remedial classes.
Parents who are educated and who value education look at what education is available for their children and decide where to live and if they put their children in private or public schools through HS. Those that realize what it takes for various college opportunities will help steer their children to the correct preparations in HS.
If a child does not have the advantages of being in a supportive household for education, and there are other disadvantages, they may have less educational opportunities and the student may also put less personal effort into their own education.
Then we have ‘common core’ and other types of programs. Some people have thrown some real junk into that program. However, since federal dollars are behind some of it, even though some of it is ‘junk’, it may get incorporated. So there are politics involved too.
One thing I could have done as a parent is check out audiotape children’s books in a second language because the early years of dual language, a child learns language differently in the early years than the later years. I didn’t feel strong enough in the second language to do this, but that would have benefited my children with a second language early. Learning it later was more difficult.
Some kids can assess their strengths and weaknesses and direct their energies accordingly, while some students just give up.
In the US, we have educational opportunities beyond other countries. You are not assessed on a track early on, if you are going to University or to trade school. We have opportunities for adults to continue their education. We have Pell Grant and other financial aid. So if someone did not have the advantages through HS, they may be able to ‘catch up’ as adults.
