No one at the district is saying why Rodriguez resigned.The chief of communications position will remain vacant for the time being, the district announced.Rodriguez replaced Jennifer Sprauge, who came to the district with Miles from Colorado and she earned even more money — $180,000 a year.

A good dealArlington School Board Trustee Tony Pompa, a successful businessman in his own right, has a deal for you: It costs the Arlington district about $5.74 per hour to educate one student, according to his caculations.Less than a Starbucks maybe, but you'd have to drink one every hour of the schoolday.Here's how he arrived at that cost, double-checked by the district's CFO:Take the 2013-14 projected budget of $467,947,038, divide it by 65,744 (the number of students), divide that by the number of instructional days (177) and the hours per day (7). Answer: $5.74A pleasant jobBefore launching into a marathon report last week on the findings of an independent curriculum audit commissioned by the Arlington school district, chief auditor Kevin Singer praised the cooperation of the staff, trustees and superintendent.It was a pleasant job, he said, since most of his work is ordered by the state, not the district.“There have been times when I have not had a good working relationship with a superintendent because he is in jail,” Singer said.
