Ms Gabrielle Ong, 18, was accepted into the course of her choice at five local and overseas universities, but she has decided to work in the tech industry instead.

Armed with zero programming knowledge, Ms Ong, who was a student in Raffles Institution (Junior College), started attending a crash course on Web development at General Assembly (GA) Singapore in February.

Having completed it earlier this month, she is now considering two offers to become a junior developer for tech companies after her paid stint as an instructional assistant at GA ends in August.

A slew of schools offering Silicon Valley-style boot camps in a range of tech-related fields are eyeing students like Ms Ong.

No relevant paper qualifications are needed, just aptitude and commitment.

These schools, which offer full- time courses lasting from seven to 12 weeks, as well as part-time courses, are hoping to attract students hungry to enter the tech industry.

The first of these to open here is GA, a New York-headquartered education company that expanded to Singapore last year.

More are to follow: Next Academy, a coding school that started in Malaysia; Alpha Camp, a technology and start-up school launched in Taiwan and Hong Kong; and Make School, a software engineering and product development school from San Francisco that bills itself as an alternative to university. They plan to open full-time courses in the next few months.

What distinguishes their programmes from traditional university computing courses is their accelerated learning model that adopts a practice-based approach.

At Alpha Camp, for example, students across all four main tracks - digital marketing, product design, Web development and app development - are expected to collaborate and put a working product together at the end of the course. There are also mentorships, networking events and career placements.

With full-time course fees ranging from $7,000 to $12,000 before applicable subsidies, these courses - which can rival the cost of a year's university fees here - do not come cheap. But the schools say that they will pay off for most students.

Mr Christopher Quek, director of Make School Singapore, said that more than 90 per cent of its graduates in the United States who are working adults either find work in the tech industry or have founded start-ups three months after graduation, while the same proportion get internship offers in the tech industry.

GA claims that globally, 99 per cent of its job-seeking graduates have found work in the fields they were trained in, or have gone on to start their own companies within six months of graduating from full-time courses.

Some students at GA Singapore are also employees who have the support of their companies to take a sabbatical from work, and return to join their businesses' digital operations.

GA has had more than 300,000 students in its global programmes so far, and over 100 in Singapore have recently graduated from or are in full-time programmes.

The high percentage of graduates who secure employment could be down to the schools' highly selective admissions process, which tests students' commitment to change and learning, and puts them through basic challenges to test their logical reasoning skills.

Next Academy admits about 10 per cent of the students who apply, and will have 15 places for its Web development boot camp next month, which will grow to a monthly intake of 40 subsequently.

Alpha Camp's acceptance rate hovers at around 20 per cent.

Mr Bernard Chan, its Hong Kong-born founder, said the boot camp's immersive approach gives a leg-up to career-switchers looking for new beginnings. "It's not just about acquiring a skill, but learning how to think differently, and understanding the mindset and culture of the industry," he said.

Could such start-up schools replace university courses in Singapore as they expand their intakes in the future?

Earlier this month, a White Paper released by the British government, aimed at reforming further education, drew fire for a proposal that will allow "high quality" start-up education providers to award degrees for a probationary period to respond to the needs of the economy.

Detractors cast doubt on the quality of education provided by new entrants, and argued that students would be penalised if course standards proved to be inadequate.

Make School Singapore's Mr Quek said it has a "vision" to accept students who are 18 years old and younger.

At Make's US headquarters, the ages of students typically range from 13 to 25.

However, it is currently targeting working adults in Singapore, and its pilot seven-week full-time app development programme for 30 students will start next month.

Mr Khoong Chan Meng, director and chief executive of the Institute of Systems Science at the National University of Singapore (NUS-ISS), which offers skills acceleration programmes for tech and digital professionals, said that whether or not these new schools will replace the traditional university or even the polytechnic model of learning is "less of an issue".

Instead, they offer a "new range of multiple pathways" that allow Singapore to address the current shortage of digitally savvy professionals.

In February, the Infocomm Development Authority noted that Singapore may find itself short of nearly 30,000 information technology professionals by next year.

But that is just "the tip of the iceberg", said Mr Khoong, as there is also demand for digitally savvy employees who can collaborate with tech professionals to develop and integrate software into the business model, which could mean that "hundreds of thousands" of such personnel are needed.

Last October,NUS-ISS started a programme called StackUp, which will join the other start-up schools in offering intensive practice- based tech courses.

It has piloted two courses in programming and Web development for 30 students in the last three months, and will refine and expand its programme to include offerings in security engineering and big data engineering in the future.

Professor Wong Poh Kam, director of the NUS Entrepreneurship Centre, noted that start-up hopefuls may need more time to develop a sound foundation in both business and technical know-how.

"Being able to build a great app alone doesn't mean that you can start a company," he said. "You also need to understand customer needs and do market validation."
