How Big Is the Bilingual Salary Premium in US Job Listings?
Preply compared average advertised pay in listings that require a language against average pay for all listings. The US result is $14,050 a year, or 18.8%.
| Measure | Annual premium | Increase over baseline |
|---|---|---|
| US, all languages | $14,050 | 18.8% |
| US, Spanish | $5,970 | 9.6% |
| Average of 18 countries studied | $9,353 | 14.3% |
Spanish is the most requested second language in US listings, ahead of Mandarin and French. It is also the largest non-English home language in the US and ranks among the world’s most widely spoken languages.
Preply puts Spanish-speaking pay at $68,162 against a $62,192 US average salary drawn from BLS earnings data. That gap is less than half the all-language figure.
US vs Other Countries in the Study
Spain tops the six-country table Preply published, at $15,291 (19.4%). The US ranks second at $14,050 (18.8%), ahead of Poland at $7,174 (18.6%).

$100, $125 or $200: California’s Bilingual Pay Differential
California pays state employees a bilingual differential of $100, $125 or $200 per pay period, set by bargaining unit. Positions must be certified as using a second language on a continuing basis averaging 10% of the time.
| Rate per pay period | Rank-and-file bargaining units | Hourly equivalent | Daily equivalent |
|---|---|---|---|
| $200 | 01, 02, 03, 04, 06, 07, 09, 10, 11, 14, 15, 16, 17, 18, 19, 20, 21 | $1.15 | $9.23 |
| $125 | 05 (California Highway Patrol) | $0.72 | $5.76 |
| $100 | 08, 12, 13 | $0.58 | $4.62 |
Units have moved to the $200 rate in stages. Unit 06 moved on October 1, 2023, Unit 10 on July 1, 2024, and Unit 18 on October 1, 2025.
Qualifying work covers conversation, interpretation and translation. The pay stops when an employee transfers to a location not designated as needing bilingual skills.
Sonoma County Prices Fluency Separately
Sonoma County’s 2023–2026 law enforcement MOUs pay $1.15 per hour for designated basic positions and $1.50 for fluent positions. The SCLEA rate was $0.95 in the 2018–2019 agreement and $1.15 in the 2019–2023 agreement, before the fluent tier existed.
Both the SCLEA and SCLEMA contracts use the same 10% work-time threshold as the state.
Salary Premium for Bilingual Teachers in Texas Districts
Fort Worth ISD’s 2025–26 budget planning proposed raising the bilingual teacher stipend from $4,000 to $5,000. The ESL teacher stipend would rise from $450 to $1,000.
| Stipend | Current | Proposed | Teachers | Budget impact |
|---|---|---|---|---|
| Bilingual teacher | $4,000 | $5,000 | 576 | $576,000 |
| ESL teacher | $450 | $1,000 | 446 | $245,300 |
The district put the combined cost at $819,500. Its market scan found a median bilingual stipend of $4,407 among the 18 of 21 comparison districts that reported one.
Dallas ISD’s proposed 2026–27 budget lifts the bilingual teacher stipend to $5,000 and sets the minimum certified teacher salary at $68,000. In 2024–25, the district’s stipend was $4,000 or $3,000, depending on position.
North East ISD in San Antonio pays up to $3,000 for bilingual teachers of record in 2025–26. Bilingual special education teachers can receive up to $4,000, and new dual-language hires get a one-time $1,000 sign-on bonus.
Who Bilingual Employees Serve: 74.1 Million Home Speakers
About 74.1 million people age 5 and older, 23% of that population, spoke a language other than English at home in 2024. Eleven languages had more than 1 million home speakers each.
| Language (age 5+) | Home speakers, 2024 |
|---|---|
| Spanish | 44.9 million |
| Chinese (incl. Mandarin and Cantonese) | 3.7 million |
| Tagalog (incl. Filipino) | 1.9 million |
Of those home speakers, 60.9% said they speak English “very well.” Among the 11 largest languages, Hindi speakers reported the highest rate at 83.5% and Vietnamese speakers the lowest at 42.6%.
State shares ranged from 2.8% in West Virginia to 45.3% in California, and the full spread appears in these bilingualism rates by US state.
ACS language data also sets bilingual election requirements under the Voting Rights Act, per USAFacts.
California requires each state office to offer equivalent services in any non-English language spoken by 4.5% or more of the limited-English public it serves. CalHR says certified bilingual employees handle most of that work.
What Proof of Language Skill Unlocks Bilingual Pay?
California’s designated bilingual positions require a score of at least level 2 in listening and speaking on the ILR scale. Unit 06 employees must also pass the state’s bilingual proficiency exam.
Dallas ISD teachers qualify through the Bilingual Target Language Proficiency Test from TEA. Professional support staff take the ACTFL OPI speaking exam instead, and both groups complete 3.5 hours of added training.
Private employers screening Spanish often ask for outside credentials, and DELE and SIELE fees and candidate numbers show what those two exams involve.
North East ISD requires full bilingual certification, though out-of-state teachers on a one-year probationary certificate also qualify. Teachers on a bilingual exception are not eligible until they earn Texas certification.
Self-study learners working toward these tests can compare Rosetta Stone and Pimsleur satisfaction scores before picking a course.
