What are the academic benchmarks for Kindergarten?

What are the academic benchmarks for Kindergarten?
For example, should my son be able to read new 3 or 4 letter words with ease and no hesitation by the end of the school year? 
What should I look out for?
Is there an article/video/podcast I could listen to to educate myself on this?

I am having very difficult mornings with my child. How do I make this better for us?

I feel like I am losing my cool with my child during the morning routine in particular . In the past, I’ve mentioned my child’s difficulty following instructions, transitioning, inattentiveness etc...
Our morning routines have been the same with small tweaks for years. I have been very regimented and routine oriented. This school year, kindergarten, in particular, is a major issue with getting ready. We try and problem solve together and we come up with good plans, but they are short lived. I know she probably can’t help it, and I want to support her and not be mad!  How do i do this?

How do I know if I am adding too much to my little ones schedule?

This year we have the option of extending my son’s usual PreK day by an hour, taking him from 1:30pm to 2:30pm, where instead of that hour continuing to serve as his quiet/decompressing time from school at home, it would be replaced with an active activity like gymnastics/sports/dance.
Should I give him another semester where we honor his usual "quiet time" block and try adding that extra hour next semester, giving him a little more time to navigate his energy levels?
Or just proceed with the extra hour of school, knowing that kids are adaptable and will eventually adjust?

How do I know my child is ready for kindrgarten?

What should we be looking for to know if my 4yo son would be ready for kindergarten or if he should repeat Pre-k 4 at a different school? He is currently doing pre-k 4 at his current school but I worry about him being the youngest but also the oldest. Thoughts?
