I have been enrolled in Claremont High School for approximately four months, and with my relatively limited experience, I can express a substantial degree of satisfaction. At the time of writing, although an ongoing pandemic has caused considerable disfunction in many educational facilities, CHS appears to be succeeding in its function of providing students with necessary knowledge. In addition, there seems to exist a consensus amongst those that I am acquaintances with that many of the assignments that are provided by teachers are creative and effective in nature. Although it should be noted that it is unlikely that I am of great reliability, due to my inexperience, I would nonetheless like to share my opinion of excellence.
CHS is the most poorly run school, and has the most incompetent school administration, that I have encountered in my 60+ years. My son, a straight A and A+ student throughout his lifetime, tells me for example that he likes his classes except for the Honors class (of all things!), because through the entire school year to date all they do is attempt to record and submit videos of themselves for purely social reasons — there is no actual schoolwork or substantive lessons on the material — and that, as a result, he hasn't learned anything at all in this class since the school year started. Indeed, in this class, no actual schoolwork has been assigned or has been susceptible to submission, because of the utter failure of the school to vet the idiotic technology randomly assigned to the student-victims. By the time of the first day of school, none of the technology had even been tried out or tested, and even the Principal himself had to re-send various links himself over and over after school opened, because of the complete lack of proactive testing, i.e., simply investing 5 minutes here or there to actually test links and so on. Sad, very sad, that the state of public education in California has slipped to this level. If you live in Claremont, CA, absolutely check out any and every available private instruction alternative to this dumpster-fire of a high school. FYI, the school administration does not even respond to e-mails sent directly to the Principal.
