Requirements to Become a Substitute Teacher for Houston Catholic School Jobs (2026)

Substitute teaching at Catholic schools in Houston can be a great fit even if you’re not Catholic. Many campuses offer smaller class sizes, clear routines, and a community culture that tends to be respectful and structured.

What’s different vs. public schools is that Catholic schools typically require Archdiocese-specific “safe environment” training (child protection) and a quick TB screening step before you can work on campus.

The 2 requirements you’ll see most often in Houston Catholic schools (for substitute teachers)

Think of this like a two-key system to qualify for Houston Catholic school jobs:

• Key 1: Safe Environment Training (online modules + background check)

• Key 2: TB Screening (questionnaire first, test only if indicated)

Once you have both, you’re usually “cleared” to accept Catholic school substitute teacher jobs in Houston.

Step 1: Complete CMGConnect Safe Environment Training (Safe Haven)

In the Archdiocese of Galveston-Houston, adults working or volunteering around students are commonly required to complete CMGConnect Safe Environment Training, which includes online training modules and a criminal background check. 

What to do

1. Go to CMGConnect (Archdiocese portal) and create an account (or sign in). 

2. Follow the prompts to enter your personal details.

3. Choose an affiliation (parish/school) and a role.

   
   

   • Example (for substitutes): Role might be “Educator” or “School personnel,” and you’ll often enter something like “Substitute Teacher” for position/area of service (exact wording varies by portal setup).

   
   

Renewal cadence

Many Archdiocese-related CMGConnect renewals are on a 5-year cycle (training + a fresh background check before expiration). 

Visualize it like a driver’s license: one-time setup, then periodic renewal.

Step 2: Complete a TB (Tuberculosis) screening questionnaire

Catholic school systems commonly use a TB Questionnaire for Adults as a first-pass screening tool. If your answers flag risk factors or symptoms, you may be asked to complete a TB test. 

What to do

• Fill out the TB questionnaire fully and honestly.

• Save a copy (PDF screenshot or download) so you can provide it quickly if a school requests it.

Put it together: a simple “Houston Catholic Schools” checklist

• CMGConnect account created

• Safe Environment training completed

• Background check submitted/completed in CMGConnect

• Training completion certificate downloaded/saved

• TB Questionnaire completed (and TB test completed if required)

Practical timing: how long this usually takes

• CMGConnect Safe Environment Training: typically about an hour-ish to complete once you’re logged in and moving (plus whatever time the background check processing takes). 

• TB questionnaire: usually 5–10 minutes.

“What do I submit, and to who?”

Schools handle compliance differently. In practice, you’ll want to keep two files ready to forward:

“Here’s my CMGConnect Safe Environment completion certificate and my TB screening questionnaire.”

That’s the fastest way to get cleared when a school (or a staffing partner) asks for documentation.
