Texas School District Bids: The Trade Contractor's Guide to Texas ISD Contracts (2026)

Texas has 1,022 independent school districts. They collectively spend more than $80 billion a year and have over $40 billion in active and approved capital bonds. For trade contractors — painters, roofers, HVAC techs, plumbers, electricians, concrete operators, fencing installers, landscapers, janitorial services — Texas ISDs are the single largest under-bid category of public work in the state. Here's the field manual.

What is a Texas school district bid?

A Texas school district bid is a formal solicitation issued by one of the state's 1,022 independent school districts, asking qualified contractors to submit pricing or proposals for a specific scope of work. The work can be anything from a single HVAC unit replacement at one campus to a $400 million construction package across 30 schools as part of a voter-approved bond.

The governing statute is Texas Education Code §44.031, which requires competitive procurement for any aggregate purchase exceeding $50,000 over a 12-month period. Most ISD procurement falls into one of six methods (covered below). The key thing to understand: Texas ISD procurement is governed by Education Code, NOT Local Government Code Chapter 252. That means the rules — bonding thresholds, M/WBE goals, procurement methods, posting requirements — are different from city or county bids.

The Texas ISD procurement landscape

MetricNumber
Independent school districts in Texas1,022
Charter school networks (district-level)8
Total K-12 public school campuses9,100+
Total K-12 students enrolled5.5 million
Total annual K-12 public school spending~$80 billion
Estimated annual ISD procurement subject to competitive bidding~$25-30 billion
Active and approved school district capital bonds$40+ billion
Average bond size for districts > 5,000 students$100M – $4B

The math: for a Texas trade contractor in nearly any market, the addressable ISD pipeline is somewhere between 50 and 200 districts (depending on travel radius), each issuing 20-500 bids per year. That's tens of thousands of relevant bid opportunities annually, against a contractor base that mostly ignores the smaller districts.

Texas Education Code §44.031 — the rules

Every Texas ISD procurement decision starts with Texas Education Code §44.031. Key provisions:

  • $50,000 aggregate threshold — any purchase of goods or services exceeding $50,000 in a 12-month period must be competitively procured.
  • Public posting requirement — solicitations must be posted in a publication of general circulation in the district plus on the district's website.
  • Sealed submission and public opening — bids must be sealed at submission and opened publicly at the announced time.
  • Award factors — districts may consider best value (not just lowest price), specifically: purchase price, reputation of the vendor, quality of the goods or services, extent to which the goods or services meet the district's needs, vendor's past relationship with the district, total long-term cost, and impact on the ability of the district to comply with HUB participation.
  • Bonding — Texas Government Code Chapter 2253 requires performance and payment bonds on contracts exceeding $100,000 (with a payment bond required above $25,000).
  • HUB participation — districts may set HUB participation goals and consider HUB status as an award factor.

The six procurement methods Texas ISDs use

Texas Education Code §44.031 explicitly authorizes six procurement methods. Knowing which method applies tells you what to expect in your bid response.

1. Competitive sealed bidding

The classic process. Vendors submit sealed pricing; the agency opens publicly; lowest responsible bidder wins. Used for clearly-defined scopes: roofing replacement, paving, HVAC unit installation, fence construction, supplies and equipment. Pricing is the dominant factor; qualifications are evaluated only to determine "responsibility" (basically: are you capable of doing the work).

2. Competitive sealed proposals

Vendors submit qualifications, a written approach, and pricing. The district scores all three. Used when quality or methodology matters as much as price: facility renovations, architectural services, integrated mechanical/electrical systems. The award factors above (best-value criteria) all come into play.

3. Request for proposals (RFP)

For professional services where price is not the dominant factor: legal counsel, audit services, architectural and engineering services, financial advisors, insurance brokers. Different scoring rubric — professional qualifications dominate.

4. Job order contracting (JOC)

See dedicated section below. JOC pre-qualifies contractors for ongoing work at agreed-upon unit pricing.

5. Design-build

The district awards a single contract for both design and construction. Used on large capital projects where speed and integration matter. Bid as a team (architect + contractor + key subs).

6. Construction manager-at-risk (CMAR)

The district hires a construction manager who acts as the prime contractor and assumes risk for the project's guaranteed maximum price. Trade subs bid into the CMAR's solicitation rather than the district's. Common on bond construction packages over $50 million.

Job order contracting (JOC) — the contractor's friend

For ongoing trade work — painting, flooring, roofing repair, HVAC service, plumbing repair, small renovations — job order contracting (JOC) is the most contractor-friendly procurement method Texas ISDs use.

Here's how it works:

  1. The district issues an RFP for a JOC contract, typically with a base term of 1 year and 1-2 renewal years.
  2. Vendors submit qualifications, a coefficient (a multiplier applied to a published unit-price catalog like RSMeans or Gordian), and pricing for any non-catalog items.
  3. The district selects one or more JOC contractors based on best-value scoring.
  4. Once awarded, the district issues individual work orders against the master JOC contract for specific projects. Each work order is priced using the published catalog × your coefficient.
  5. Work orders typically range from $5,000 to $750,000 each. You execute them on the district's schedule.

Why JOC matters for trade contractors:

  • One competitive process gets you a year (or three) of steady work across dozens of campuses.
  • Unit pricing means you don't re-bid every small job.
  • The district's project manager calls you when work comes up — no need to monitor every solicitation.
  • Margins are typically better than ad-hoc bids because the unit-price catalog includes contractor overhead.

Most large Texas ISDs (HISD, DISD, Cy-Fair, Katy, AISD, NISD, FWISD) have multiple active JOC contracts for different trades. Winning one is the single highest-value ISD bid you can pursue.

Bond programs — where the big money is

Voter-approved bond programs fund the lion's share of Texas ISD capital work. Currently active and approved Texas school district bonds total more than $40 billion. Major active programs:

DistrictMost recent bondAmountActive through
Houston ISD2024 bond$4.4 B2030
Cypress-Fairbanks ISD2019 bond$1.76 B2027
Northside ISD (SA)2022 bond$992 M2030

Socorro ISD (El Paso)2019 bond$445 M2028
El Paso ISD2016 bond$668 M2026-2027

For trade contractors, the universal bond categories are:

  • HVAC system replacements — easily the largest single category. Most TX school facilities built 1960s-1990s have aging rooftop units due for replacement.
  • Roof replacements — 15-25 year cycle, large pipeline across every district.
  • Classroom and facility renovations — flooring, painting, ceiling tile, lighting upgrades.
  • Athletic facility construction — stadiums, fieldhouses, tracks, sport courts. Especially relevant in Texas where football and band facilities are voter-favored bond items.
  • Security upgrades — secure vestibules, ID-card access control, cameras, fencing. Post-Uvalde, every Texas ISD bond has substantial security work.
  • New school construction — typically CMAR delivery; trade subs bid into the prime's solicitation.
  • Transportation — bus replacement, fleet maintenance facilities.

Background check & fingerprinting requirements

Texas Education Code §22.0834 requires every contractor employee who will have direct contact with students or be on school district property during school hours to undergo a national criminal history records check including fingerprinting.

Practical implications:

  • Every worker in your crew needs a fingerprint clearance, not just the supervisor.
  • Cost: typically $40-50 per worker through the Texas Department of Public Safety (DPS).
  • Time: 5-10 business days for the DPS check; some districts use third-party clearinghouses that take longer.
  • Validity: clearances are typically valid 2-3 years, and reciprocal across districts using the same clearinghouse vendor.
  • Disqualifying offenses: certain felony convictions automatically disqualify a worker. Sex offenses are universally disqualifying. Felony theft and violence convictions within the past 10 years are typically disqualifying. Misdemeanor convictions are usually evaluated case-by-case.

Build a 2-3 week onboarding lag into your bid timeline. If a project starts before your crew's clearances are processed, you can't put workers on site.

MWBE participation in Texas ISDs

Most large Texas ISDs administer their own M/WBE (Minority/Women Business Enterprise) or HUB (Historically Underutilized Business) certification programs. Common goals: 15-32% participation on procurement.

For trade contractors:

  • If you qualify as M/WBE/HUB (51% minority or woman-owned + Texas-located), apply for certification at the State of Texas HUB level through the Comptroller's office — most ISDs reciprocally recognize state HUB.
  • If you don't qualify, partner with certified M/WBE subs to fill your prime bid's participation requirement. Primes actively recruit certified subs for this reason.
  • Several Texas ISDs (HISD, DISD, NISD, FWISD, AISD) have searchable M/WBE vendor directories — primes use these when building participation plans.

Trade-by-trade ISD bid categories

Painting & coatings

Every district bond includes scheduled exterior repaints. Most large ISDs maintain JOC contracts for ongoing interior repaints and small touch-up work. Major district programs typically repaint each campus on a 7-10 year cycle. Pavement and curb striping at parking lots and bus drives is also continuous. Browse current Texas painting bids →

HVAC & mechanical

The largest single ISD trade category. Most TX school facilities built 1960s-1990s have aging rooftop units. Bond programs typically replace 5-15 schools' HVAC per cycle. JOC contracts cover routine service. Browse current Texas HVAC bids →

Roofing

15-25 year replacement cycle drives steady bond-funded work. Roof repair JOC contracts cover leaks and small repairs between full replacements. Texas weather (hail in DFW, hurricanes in coastal districts) creates emergency procurement spikes. Browse current Texas roofing bids →

Flooring

Carpet, VCT, athletic flooring (gym wood + rubber for fitness rooms), and stage flooring. Most districts have JOC contracts for ongoing replacement. Bond programs include full-facility re-flooring at renovated campuses. (See trades dashboard →)

Plumbing

Bond-funded full facility upgrades, JOC contracts for ongoing repairs. ADA-compliance restroom upgrades are a continuous program in most districts. Athletic facility plumbing (locker rooms, training rooms) is a growing category. Browse current Texas plumbing bids →

Electrical

Bond-funded lighting upgrades (most districts converting to LED), classroom power upgrades for tech, panel replacements at aging campuses. Security and access-control electrical (huge category post-Uvalde). Browse current Texas electrical bids →

Most large districts contract out grounds maintenance at all campuses — multi-year contracts typically valued $500K-$5M per year per district. Athletic field maintenance (football, baseball, soccer turf maintenance) is often a separate contract. Browse current Texas landscaping bids →

Janitorial

Most large Texas ISDs handle janitorial in-house but contract out specialty work (deep cleaning, floor stripping/waxing, post-construction cleaning). Smaller districts often contract out full janitorial services. Browse current Texas janitorial bids →

Security & access control

Post-Uvalde, every Texas ISD bond includes substantial security work. Categories: secure vestibule construction, card-access systems, CCTV/camera systems, panic-button systems, perimeter fencing, classroom door hardware upgrades, and exterior lighting. This is one of the fastest-growing ISD bid categories. Browse current Texas security bids →

How to win Texas ISD bids — six tactics

  1. Pursue JOC contracts first. Winning a single JOC contract typically generates 5-50 work orders over the contract term — more than you'd win bidding individual jobs. Worth the effort even though the qualifications package is more involved.
  2. Register with at least 10-20 districts in your radius. Most contractors only register with the closest 2-3 districts. The smaller districts have less competition.
  3. Get HUB-certified or partner with HUB subs. Even on competitive sealed bids, HUB status is one of the explicit best-value award factors under Texas Education Code §44.031.
  4. Build a clearance-management process. Don't lose a job because your crew's fingerprint clearances aren't ready. Have your standard crew pre-cleared with the major districts you bid into.
  5. Attend pre-bid conferences for every job you bid. ISD project managers remember vendors who show up. Many give informal scope guidance at pre-bid that doesn't make it into the addendum.
  6. Specialize in bond cycles. Major Texas ISDs run bond programs that drive 5-7 years of capital work. Identify districts with active bond programs in your trade and prioritize them.

Five mistakes new ISD bidders make

  1. Bidding without understanding bond timing. Bond projects run on school-calendar timing. Summer work bids in February. New construction bids 12-18 months ahead. Reading the bond program calendar saves you from bidding work that's already been awarded.
  2. Underestimating background-check lead time. Build 2-3 weeks into your project schedule for crew clearances. Better: pre-clear your standard crew with the districts you target most.
  3. Treating ISDs like cities. Different procurement code, different bond approval process, different award factors, different bonding thresholds. Texas Education Code §44.031 reads differently from Texas Local Government Code Chapter 252 even when the work looks identical.
  4. Skipping the smaller districts. Aldine ISD, Round Rock ISD, Klein ISD, Pasadena ISD, Garland ISD, Spring ISD, Mansfield ISD, Pflugerville ISD, and dozens more each procure $100M-$500M annually with far less national competition than HISD or DISD.
  5. Not building a relationship with district facility managers. Bond work is competitively bid, but emergency work (a leaking roof, a broken chiller) is usually delegated to facility managers who call vendors they know. Get to know them.

Frequently asked questions

Do Texas school district bids have a minimum dollar amount?

The competitive-bidding threshold under Texas Education Code §44.031 is $50,000 in aggregate over 12 months. Below that, districts have discretion to use informal procurement (purchase orders, sole source, or quotes from a few vendors). Above that, the formal competitive process is required.

Can I bid on Texas ISD work from outside Texas?

Yes. No residency requirement for ISD vendors. However, Texas ISDs often prefer in-state vendors for award factors like "vendor's past relationship with the district" and HUB participation. Out-of-state vendors typically partner with a Texas-located sub to strengthen the bid.

What's the typical bid window for an ISD solicitation?

Most Texas ISDs run a 21-30 day bid window from posting to opening. CMAR and design-build solicitations sometimes run 45-60 days. Emergency procurements (storm damage, leaking roofs) can run as short as 7-14 days.

How does charter school procurement differ from ISD procurement?

Texas charter schools operate under different procurement rules — they're not subject to the same Texas Education Code §44.031 requirements, but they typically follow similar competitive procurement processes. Larger charter networks (IDEA Public Schools, KIPP Texas, Harmony Public Schools) procure similarly to mid-sized ISDs.

What's the average award timeline for a Texas ISD bid?

For a typical competitive sealed bid: 21-30 days from posting to opening, 14-21 days for administrative review and recommendation, then approval at the next regular board meeting (usually monthly). Total: 45-75 days from posting to award. Bond projects often add another 30-60 days for contract execution and notice to proceed.

Do Texas ISDs use BidNet or DemandStar?

Some districts syndicate their bids through BidNet or DemandStar, but every ISD bid is also published — for free — on the district's own portal as required by Texas Education Code §44.031. Paying for an aggregator subscription for bids you can get free directly is the most common new-vendor mistake.

Where can I find a list of all Texas ISDs?

The Texas Education Agency (TEA) maintains the official list of all 1,022 Texas independent school districts. The Texas Comptroller's Local Government Transparency portal includes ISD spending data. MuniBidBoard aggregates active solicitations from as many districts as our scrapers can reach.
