While no one expects stricter dress codes at a few area campuses to directly affect academic test scores this year, it’s clear students appear far more focused and sharp.

The dress code changes — which went into effect at University High and La Vega High schools — are a reflection of the success that last year’s dress code at Waco High prompted.

School officials went so far as to credit the stricter code at Waco High with boosting student performance. Waco High principal Clarence Simmons told Trib education reporter Wendy Gragg that it “added the focus on academics that we wanted.” Or as he proudly told us of students: “They look sharp. They look so awesome. They are looking very professional.”

That’s what we all want.

And if it takes getting rid of sagging pants, dragging jeans, disturbing graphics on T-shirts or threatening insignias, then this move is well worth any resistance.

When school started Aug. 23, students at La Vega and University High were no longer allowed to wear any denim (pants or skirts) except for certain days like Spirit Fridays. And on those days skinny jeans and jeans with tears are not permitted. Instead, khaki, navy, brown, black or white slacks are now the rule most days.

Students also must wear only solid color shirts. At La Vega and Waco High the shirts must have collars — a rule that University will embrace in August 2011.

Texas is among 21 states plus the District of Columbia where lawmakers have authorized local school districts to adopt dress codes, according to the Texas Education Commission of the States, a nonprofit group that helps state leaders shape policy. There are documented advantages educators have seen from dress codes and school uniforms. These include: decreased violence and theft, such as of costly designer clothing or expensive sneakers; reduction in gang-related insignia; and less peer pressure. Plus dress codes help school officials recognize intruders on campus, assist students in concentrating on their school work and, finally, help instill discipline.

We especially praise the last two attributes. Our students have so many distractions and obligations nowadays, why make it harder for them?

Let’s help them focus. And if something as simple as a dress code creates an environment where learning is the focus, then let’s readily adopt it.

And it shouldn’t just apply to students.

Midway ISD also changed its staff dress code this year, spokeswoman Traci Marlin tells us. Now, male staffers are allowed to have facial hair (although students still may not) but it must be neatly kept. Also men don’t have to wear ties this year and staff are not allowed to wear flip flops or jeans (except for special spirit days).

The district is pushing a more current, professional appearance among its staff. “The whole idea is to set an example for the children,” Marlin said.

Great idea. Let’s all set an example and spiffy up and wear sensible attire.

Who knows? It might help us all focus a bit more.
