Several Central Texas schools have seen allegations of improper relationships between teachers and students in recent weeks.

Many times, it starts with technology: texting, emailing, or social media.

Authorities on June 3 arrested Hutto ISD teacher and football coach Jake Fenske, 26, after police said he had a sexual relationship with a 16-year-old student. Court documents show the two communicated through texts and Snapchat.

In 2015, Round Rock ISD McNeil High School teacher and coach Christopher Cotten was accused of sending inappropriate messages to a 16-year-old girl, including nude photos.

Both districts have policies on the technology. Hutto ISD, the employee handbook lays out strict guidelines.

They look at things like the timing and amount of communication. If a teacher sends a text message to a student, it must include the student's parent or a school supervisor on the message. The district also said their teachers go through training on how to use technology appropriately.

Round Rock ISD's policy is similar, and states employees can only use the technology to communicate with students about matters in the scope of the employee's job.

Stephanie Jacksis with the Association of Texas Professional Educators said they encourage teachers to create separate accounts for school use.

"We want the relationship to be very clear and very professional between teachers and students,” said Jacksis.

She said it can be a great learning tool.

"We want kids to be tech-savvy so they are career ready," said Jacksis.

Shauna Allen is a kindergarten teacher at Reagan Elementary in Leander ISD. Allen tweets photos of what the kids are doing in school and encourages parents to follow along.

"It gives them that look into the classroom that they don't see every day," said Allen.

The school even promotes the medium to the students, teaching them to use it wisely from a young age.

"Looking at it from a professional aspect it is very positive,” said Allen.

And that's the key: keeping it professional.
