Study English online with Texas State faculty: the OTSIE programme at US$900 per level

Most online English courses are pre-recorded video. OTSIE differs in three ways, and the third is the one that matters most for anyone planning to study in the United States.

What OTSIE is

Online TXST Intensive English (OTSIE) is the online version of the TSIE intensive English programme at Texas State University — a public university in San Marcos, Texas, between Austin and San Antonio.

• Taught live over Zoom by Texas State's own faculty — full-time and adjunct instructors, real scheduled classes rather than recordings.
• All six skill areas: reading, vocabulary, grammar, writing, listening and speaking.
• It counts as proof of English proficiency if you go on to enrol at Texas State. That is the decisive part: you build the entry requirement while you learn, instead of finishing the course and still needing an IELTS sitting.

Four levels, placed by test

The programme offers levels 2 to 5 of the TSIE sequence. You take a placement test at the start to determine your level — you do not choose it:

• Level 2 — Low-Intermediate: foundations of academic presentation, vocabulary development, pronunciation and note-taking; you begin writing academic paragraphs with topic, supporting and concluding sentences.
• Level 3 — Intermediate: different rhetorical modes of academic presentation, subject-specific vocabulary, comprehension of longer texts, advanced paragraphs and basic essays.
• Level 4 — High-Intermediate: advanced work across all four skills, focused on organisational structure and critical thinking. There is an evening track with an academic and professional focus, using presentations, debates and case studies.
• Level 5 — Advanced.

Materials are authentic — TED Talks and the like — across technology, business, environmental studies, sociology, economics and design.

Each level runs about 15 weeks.

Class times across time zones

Classes run in both the US morning and the US evening to reach multiple time zones. Converted to Vietnam time (UTC+7), the pattern is favourable:

• US morning classes (Mon/Wed/Fri, 5–7 a.m. or 6–8 a.m. US Central) fall around 7–9 p.m. in Vietnam — after work or after school.
• Tuesday/Thursday classes (5–8 a.m. or 6–9 a.m. Central) fall around 7–10 p.m. Vietnam time.
• US evening classes (Mon/Wed/Thu, 6–8 p.m. Central) fall around 7–9 a.m. the next morning in Vietnam.

Check the official calendar before enrolling: US and Vietnamese daylight-saving changes do not line up, so the offset shifts twice a year.

Terms and deadlines

Per the published calendar, the next intake open for applications is Spring 2027:

Level group	Term dates	Application due
Levels 2 – 3	20 Jan – 28 Apr 2027	15 Jan 2027
Levels 4 – 5 (high school)	20 Jan – 28 Apr 2027	15 Jan 2027
Levels 4 – 5 (college & adults)	19 Jan – 27 Apr 2027	15 Jan 2027

Placement exams are held on 15–16 January 2027. Applications for Fall 2026 closed on 10 August 2026.

Application and cost

• No application fee.
• No documents other than a photo ID are required for admission — no transcripts, no certificates.
• US$900 per level.

Two conditions to be clear about before transferring money: the fee must be paid before classes begin, and it is non-refundable. Confirm the schedule works for your time zone first rather than enrolling and sorting it out later.

Because you study online from home, no student visa is required and there are no housing or airfare costs — a materially different proposition from travelling to the US for language study.

Who it suits

• Applicants targeting Texas State University who fall short on English — OTSIE raises the level and satisfies the requirement at once.
• Students who want to meet a US academic environment before they fly, so the first year is less of a shock.
• Working professionals needing academic and professional English; the Level 4 evening track is built for that.
• Families who want to test how a student copes before committing to the full cost of a degree abroad.

Weigh it honestly: this is an English course, not a degree programme, and it carries no university credit. If you need a certificate that many institutions accept, IELTS or TOEFL remains the more portable route — see standardized tests.

Next step

VNIS helps you gauge the right level, pick a schedule that fits your day, and plan the route into degree study in the US afterwards. See study in the USA, or request a free consultation.
