As a teacher in K-6 for almost 20 years I grew very opposed to standardized testing. For 1st graders I spent at least 50% of my time testing students 1:1 while the rest of the class educated themselves. This started on the first week of school, even though they had been tested at the end of the year before...they hadn't been in school over vacation but we had to test anyway. This was throughout the year, constant testing. It was beyond ridiculous.
