Why You Need a Mandatory Alcohol Server Training (MAST)

The Mandatory Alcohol Server Training (MAST) certificate is a non-negotiable state law requirement for any restaurant in Washington selling alcohol for on-premises consumption. The legal authority is the Washington State Liquor and Cannabis Board (WSLCB), governed by the Washington Administrative Code (WAC) 314-17, specifically WAC 314-17-010 through WAC 314-17-100. This code section mandates that any person who mixes, serves, sells, or supervises the sale of alcohol must obtain a valid MAST permit. It is the restaurant owner’s responsibility to ensure all alcohol-handling staff are trained and certified before they interact with customers, and you must keep proof of valid permits on-site for inspection by the WSLCB.

Operating servers without valid MAST certificates puts your entire business at immediate and severe financial risk. Based on WSLCB enforcement data, common penalties for non-compliance include:

  • Administrative fines of up to $1,000 per violation for the business owner, and fines for individual servers, with costs escalating for repeat offenses.
  • Mandatory license suspension of your liquor license, typically ranging from 3 to 30 days for a first violation, which forces a full-service shutdown.
  • License revocation for severe or repeated offenses, permanently ending your ability to sell alcohol.
  • Increased liability exposure, as your commercial insurance may deny claims related to an alcohol incident involving an uncertified server, and your lease may be jeopardized if liquor sales are a stipulated part of your business operation.

Legal code: State liquor control act, server training requirements, age verification laws

License suspension (3-30 days typical), revocation, fines ($1,000-$10,000+), criminal prosecution for sales to minors

Recent update: As of 2026, the WSLCB requires all new MAST applicants to complete an updated training module covering intervention techniques for over-service and recognizing fake identification, reflecting recent changes to WAC 314-17-035.

High rejection risk

Government ID Number

text
Auto-filled from compliance interview

Enter the number from the primary ID used for age verification, such as a Washington State driver's license or ID card number.

Top 5 Mandatory Alcohol Server Training (MAST) Mistakes

1

1. Selecting the Wrong Certification Course Provider

Taking a course from a provider not approved by the Washington State Liquor and Cannabis Board (WSLCB) results in a worthless certificate. The WSLCB only accepts training from their list of authorized providers. If you submit an unapproved certificate, your application is immediately invalid, and you must retake the entire course with an approved vendor, adding 1-2 weeks and the cost of a second course.

2

2. Mismatching Information Between MAST Certificate and Application

The full legal name, date of birth, and ID number (like a Driver's License) on your MAST certificate must match the information you provide on your liquor license application exactly. A mismatch—like a nickname ("Rob" vs. "Robert") or a transposed date—triggers a verification failure. This adds 2-3 weeks to your timeline while you get the certificate provider to issue a corrected document and resubmit.

3

3. Letting Server Certifications Expire Before Renewal

MAST certification is only valid for five years from the issue date. Servers who continue to work with an expired certificate are in violation, risking individual fines up to $1,000 and placing the entire establishment's liquor license in jeopardy. A renewal course is required before the expiration date to maintain compliance; the new certificate must be on file before the old one lapses.

Complete a State-Approved MAST Course

Enroll in and pass a Liquor and Cannabis Board (LCB) approved Mandatory Alcohol Server Training program. This can be an in-person class in Spokane or an online course from an authorized provider. The course typically takes 4-5 hours and covers Washington law (RCW 66.20.310), ID checking, and intervention techniques. You must receive a passing score on the final exam to get your MAST permit card.

4-6 hours
2

Receive Your MAST Permit Card & Add to Your LCB Profile

After passing the course, your provider will issue you a MAST permit card with a unique permit number. You must then log into the Washington State LCB's online system (LEAP) or have your employer add this permit number to your individual server profile. This links your certification to your employer's liquor license, which is required for you to legally serve. Do not start serving until this step is complete.

Employer Verification & Record-Keeping

Your employer (the liquor licensee in Spokane) must verify your MAST permit is active and on file with the LCB before you begin serving alcohol. They are required by law (WAC 314-11-050) to keep a record of all servers' MAST permits, either electronically or as a physical copy, available for LCB inspection. Failure to have this documentation can result in fines for the business.

FAQ

Timing for the Mandatory Alcohol Server Training (MAST) varies significantly. You must complete the state-approved training course, which can be done online or in person, with providers often offering instant or same-day certification. However, you must provide this server training certificate to the Washington State Liquor and Cannabis Board (WSLCB) before any employee serves alcohol, and it must be maintained on-premises. To operate legally, you must also hold a valid City Business License/Registration, which has its own separate timeline. Contact the WSLCB or your training provider for current processing details.

The Washington State Liquor and Cannabis Board (WSLCB) does not charge a direct government filing fee for the Mandatory Alcohol Server Training (MAST) certification itself. However, you must pay a fee to an approved third-party training provider for the course, which typically ranges from $15 to $40 per employee, according to provider websites. This is separate from other required fees, such as those for your Building Permit. Not legal advice — verify course costs with approved WSLCB providers.

No, MAST certification is issued to individual servers, not locations, and is portable with the employee. A server's valid MAST permit is recognized statewide, so if an employee transfers to your new restaurant location in Spokane, their certification remains valid. You are responsible for verifying that all alcohol-serving employees have current MAST permits and keeping their certificates on file at your business, per WSLCB regulations (WAC 314-11-050).

Mandatory Alcohol Server Training (MAST) certification expires five years from the issue date, as stated in Washington Administrative Code (WAC 314-11-050). Each server must complete a recertification course before the expiration date to remain legally permitted to serve alcohol. Failure to renew on time requires the employee to retake the initial training course, which can delay their ability to work. Contact an approved WSLCB training provider for renewal scheduling.

There is no physical 'inspection' for the MAST permit itself. During routine compliance checks by the Washington State Liquor and Cannabis Board (WSLCB), agents will verify that every employee serving or selling alcohol has a valid, unexpired MAST certificate physically available on the premises for inspection. Agents may also quiz employees on responsible service practices taught in the MAST program. Non-compliance can result in fines for the business and the individual server.
