Bilingual pay differential for NEMT drivers and dispatchers: amounts, proficiency tests, and overtime

A bilingual pay differential works best when it is tied to the assignment, tested before it is paid, and counted in the overtime rate. There is no legal amount, so most companies start from a public benchmark and their own budget. The rule that makes the topic matter for NEMT is the language access rule for Medicaid providers, covered in the language access guide: a driver or dispatcher can speak with a rider in another language without an interpreter only after the company has designated them and they have shown they are proficient. Paying for that skill is the other half of the job. The overtime math is in the overtime guide.

What should a bilingual pay differential be?

There is no required amount. A public schedule is a useful benchmark, and one detailed example is California state government’s. Its Pay Differential 14 (revised October 14, 2025) pays a monthly amount to employees in positions that use a second language:

• $100 a month for rank-and-file classes in bargaining units 08, 12 and 13, in effect since July 1, 1999, which the schedule converts to $0.58 an hour or $4.62 a day.
• $125 a month for the California Highway Patrol, in effect since October 1, 2024: $0.72 an hour or $5.76 a day.
• $200 a month for most other bargaining units, phased in unit by unit from October 31, 2019 to October 1, 2025: $1.15 an hour or $9.23 a day.

Those are one public employer’s rates, listed by bargaining unit, and not a market rate for NEMT staff. What carries over is the structure. The schedule pays a flat monthly amount, prorates it when an employee qualifies for only part of a pay period, and also states the amount as an hourly and a daily rate. A company can choose a monthly or an hourly form, as long as it applies the choice the same way to everyone in the role.

As an example of cost, two drivers paid a $1.15 hourly add-on for 2,080 hours each cost $4,784 a year. The same two drivers on $200 a month cost $4,800.

Who should get the differential?

The staff whose jobs use the language on a regular basis should get it, not everyone who speaks it. California’s schedule gives the clearest test. The position must be certified by the department as one that requires bilingual skills on a continuing basis averaging 10 percent of the time. That counts conversation, interpretation and translation, plus closely related work done directly with those transactions.

Three other rules from the schedule carry over to a van company:

• Pay follows the duties. When a duty change means the employee no longer qualifies, the department must notify the State Controller’s Office immediately so the pay stops.
• Keep the pool small. Where practical, the bilingual responsibility is placed in as few positions as possible, so the extra pay goes to the people doing the work.
• Keep files. Departments must keep information on every position that qualifies, so the pay can be audited.

For NEMT, a dispatcher who answers calls in Spanish most days should pass a 10 percent test easily. A driver is a closer call. A driver who speaks the language but is rarely assigned riders who need it does not use it often enough, and a driver on a route with many such riders may use it all day. To measure it, list the calls and trips handled in the language over two typical weeks, add the minutes, and divide by hours worked. A standing order with the same rider every week makes the count easy.

Which employees count as qualified bilingual staff?

Under the Section 1557 rule, qualified bilingual staff are employees the company designates to give oral language help as part of their current job, who have shown the company that they are proficient and able to communicate accurately and impartially. The definition in 45 CFR 92.4 has two parts:

1. The employee is proficient in speaking and understanding both English and at least one other language, including any necessary specialized vocabulary, terminology and phraseology.
2. The employee is able to communicate effectively, accurately and impartially, directly with individuals with limited English proficiency in their primary languages.

Under 45 CFR 92.201(e), a covered entity must not rely on staff other than qualified interpreters, qualified translators or qualified bilingual staff to communicate with riders who have limited English proficiency. The Office for Civil Rights added two points when it published the rule. Calling oneself bilingual is not enough, and being able to interpret is a separate skill. A person you allow to interpret has to meet the interpreter definition on its own.

The rule does not require extra pay. The Office for Civil Rights wrote that it “encourages covered entities to provide training and compensation opportunities to support professional development for bilingual/multilingual staff.”

How do you test proficiency?

The rule leaves the method to the company. The Office for Civil Rights said covered entities have flexibility in how skills are assessed, should set processes to determine them independently, and should assess them periodically. A practical test follows the two parts of the definition:

1. Write the script from real rides. Use 10 to 12 prompts a driver or dispatcher actually needs: confirming a pickup window, asking for the address and door, explaining a late arrival, handling a no-show, giving the seat belt and securement instructions, and explaining a wheelchair lift. This covers the “specialized vocabulary, terminology and phraseology” part.
2. Test both directions. The candidate speaks, and also listens to a sentence from a rider and answers it. The rule says speaking and understanding.
3. Have someone fluent in both languages score it. The scorer should have no stake in the result, so not a relative or a close friend of the candidate.
4. Score accuracy and impartiality. Check that the person says what was meant, without adding or leaving out anything. That is the second part of the definition.
5. Record it. Write the name, language, date, scorer and result in the written procedure, as the language access plan template does.
6. Retest on a schedule. The rule says periodically and sets no interval, so choose one, such as yearly, and write it down.

California’s state example shows a formal version. For one bargaining unit, employees must pass the State’s bilingual proficiency exam and be required by a supervisor to use the skill on a continuing basis before they receive the pay.

Does the differential count toward overtime?

Yes, for employees covered by federal overtime rules. 29 CFR 778.108 says the regular rate includes all remuneration for employment, except seven statutory exclusions, and that the parties cannot declare what the regular rate is. 29 CFR 778.207 says extra premiums for night work and for hazardous, arduous or dirty work must be included, and that lump-sum premiums paid without regard to hours must be included too. A bilingual differential is pay for the work itself and fits none of the seven exclusions, which cover gifts, pay for time not worked, discretionary bonuses, benefit plan contributions and overtime-type premiums (29 CFR 778.200).

California’s own schedule shows the same approach. Its table of benefit pay marks overtime as “No/Yes (FLSA),” which indicates that the differential counts toward the overtime rate for employees covered by the federal wage law. Colorado’s overtime order lists shift differentials, non-discretionary bonuses and similar pay as part of the regular rate (Rule 1.8.1).

Example: hourly add-on

A driver earns $18.00 an hour plus a $1.50 bilingual add-on and works 44 hours in the week. This is an example, not a market rate.

1. Straight-time pay: 44 hours x $18.00 = $792.00, plus 44 hours x $1.50 = $66.00, for $858.00.
2. Regular rate: $858.00 / 44 = $19.50.
3. Overtime premium: 4 overtime hours x ($19.50 / 2) = $39.00.
4. Total for the week: $897.00.

A common mistake is to figure the premium on the base wage only: 4 x ($18.00 / 2) = $36.00, for a total of $894.00. That is $3.00 short for the week, and the gap repeats every overtime week for every bilingual employee.

Example: flat amount for a pay period

A driver receives a flat $200 that covers a four-week pay period and works 44 hours in one of those weeks. The amount is spread across the weeks it covers, which gives $50 for the week. Divided by 44 hours, that adds about $1.14 to the regular rate for that week. Half of that, about $0.57, is owed for each of the 4 overtime hours, which is about $2.27 on top of the regular overtime pay. 29 CFR 778.209 describes this method for bonuses paid over a period longer than a week.

Mistakes that cost money or break the rule

Five mistakes put the company outside the rule or cost it money:

• Paying everyone who says they speak Spanish. Self-identification is not proof of proficiency, and a differential for a skill nobody tested is hard to defend.
• Letting an untested driver interpret because they are paid for it. The differential does not make someone a qualified bilingual employee. The designation and the demonstrated proficiency do.
• Leaving it out of overtime. The weekly difference looks small, and it adds up across a roster.
• Paying after the job changed. If a dispatcher moves to a role that does not use the language, stop the differential as California’s schedule does.
• Asking a bilingual driver to interpret between a rider and clinic staff. Interpreting is a separate skill under the rule, so anyone you ask to do it has to meet the interpreter definition.

Hours behind the pay math

Drivers clock in and out in the HealthRide driver app, and the driver and timecard reports show how many hours each driver worked. Those hours are the numbers behind the overtime math above, so the weekly hours you divide by come from real clock-ins instead of memory.
