good article about Shortage Occupations from skillspanorama (10/2016):
“The ICT sector is constantly gaining importance in Luxembourg. It represented around 7% of the total national Gross Value Added in 2013, which is one of the highest shares in Europe. There were approx. 17 thousand employees in ICT at the end of 2014, which represents approx. 5% of total employment.  Increasing demand can be explained by the expansion of the sector. A significant share of ICT companies support other industries, but within the ICT sector itself areas are developing, like the recent boom in data centres that allow internet download and streaming services.
Shortages relate to recruitment difficulties: in 2014, approx. 58% of enterprises which recruited or tried to recruit staff for jobs requiring ICT related skills reported problems in filling these positions, compared to 53% in 2012.  There are assumptions that Luxembourg’s national policies do not care enough about ICT in education, both for primary and secondary schools.
A school survey conducted by the European Schoolnet in 2012  noted a paradox: on one hand, Luxembourg has 96% of its households (with children involved in compulsory education) equipped with ICT devices and internet connectivity; on the other hand, although teachers report to be self-confident in ICT use, many of them do not consider ICT competence in their work plan. 
The government launched the strategy “Digital Luxembourg”, where the main objective is to reinforce and consolidate the position of the country in the ICT sector. One element of this strategy includes making the Grand-Duchy attractive for a foreign-qualified workforce.  In addition, Luxembourg has lowered the salary threshold in certain professions in the ICT sector so more people can obtain the ‘EU Blue Card’ . This encourages companies to recruit more highly skilled third-country nationals wishing to settle in the Grand Duchy and having the profile of developers, programmers, analysts and ICT project supervisors. To serve the interests of ICT professionals, on July 15, 2014 “ICTLuxembourg” was established.
It is the main active umbrella organisation in the ICT sector serving the interest of its members.  In 2015, the Luxembourg PES launched a new partnership with the company NumericAl that uses the WebForce3 methodology to enhance ICT skills. A first result of this partnership is the training programme “Fit4Coding” that is co-financed by the European Social Fund. Over a time period of 18 months, 90 web developers will be qualified in a way that they can immediately enter the labour market as a web developer or junior integrator after having successfully completed the training programme. The first “Fit4Coding” training cycle started in November 2015 with 17 jobseekers who have received intensive training of 490 hours in 3.5 months to prepare skills needed in the field of ICT. The Fit4Coding initiative thus helps to close the gap between the profiles of jobseekers registered with the PES and the demand in advanced technologies in future years .”
