Leaving something out by letting ego get in the way

Yesterday Tom Peters commented about a recent story he ran across in a newspaper. It was a quote from a local high school principal commenting on higher test scores on a standardized math test. The quote read:

"The significant jump is due to the hard work and dedication of our teachers and administrators - and is not the typical increase one would expect in a year."

I'll ask the same question Tom does: What is wrong with this quote? Do you see it - or rather, do you see what is missing?

The corrected version, as Tom points out, should read like this:

"The significant jump is due to the hard work and dedication of our students, teachers and administrators - and is not the typical increase one would expect in a year."

Many kudos to Tom for noticing this and bringing to the attention of his readers.
