I have a question regarding the 5th kinder class at Huff and Bubb. Is it correct that next year when my son goes to 1st grade there will be a 5th 1st grade class?

@Huffparent: They will probably add another first grade next year but be careful because my son's school (at another school in the district) only carried the extra class for a few years. Now he has 32 kids in his fourth grade class.

The MVWSD has had a multi-decade demographic profile of loosing 3% of enrollment per year per grade level advancement (K-to-5th). The last several districtwide demographics reports, starting in about 2013, have shown this same effect. Los Altos does not show this trend.
It is generally considered, although the data from multiple research reports is not entirely consistent, that small class sizes, above about 3rd grade are not statistically related to better academic achievement. More important is: experienced good teachers! With the lowest teacher retention numbers in the county (ave years of tenure in district), the MVWSD problems are more in retaining good teachers - rather than having 4th and above classrooms with a smaller number of students.
Should wealthier-area parents, like Huff, have smaller class sizes for their kids?

The research data does suggest (not the greatest statistical certainty however) that smaller class sizes ONLY MATTER for K-3rd grade kids from Economically Disadvantaged families. I assume Huff parents, have experience with how many college educated parents can volunteer in-class at their school - this does not happen in the areas with poorer families.

I disagree. I don’t care how intelligent parents are, I don’t want 32 or more kids in my child’s class! My 4th grader had 27 in Los Altos. No one can tell me that 5 extra kids don’t make a difference for the teacher.
