The TES is the number one source for teachers looking for a new job, according to research commissioned by the Department for Education and Skills.
It shows that almost two-thirds of all teachers searching for a job use The TES and half log on to the website www.tesjobs.co.uk.
The annual survey, conducted among teachers, support staff, council officers and parents, confirmed that The TES remained the top source for job-seekers.
The TES is most popular with secondary teachers, with three-quarters using the newspaper to find a job and more than half (53 per cent) using the website.
The research comes as independent online user figures for the month of April show that www.tesjobs.co.uk now has more than 300,000 users for the first time, an increase of 13 per cent.
Patrick Roberts, advertisement directorof The TES, said: "With so many jobs every week in the paper and online, and with our reputation for authoritative, cutting-edge education news, it is not surprising The TES is the first port of call for job-seekers and employers.
"When teachers are looking for a job, they can rely on The TES to offer the most comprehensive and extensive opportunities, week in, week out."
The report, compiled by the Central Office of Information on behalf of the DfES, also highlights the increasing popularity of The TES as a source of education information.
The proportion of local authority staff who use The TES as their main source for education news more than doubled from 9 per cent in November 2003, to 21 per cent last year.
Meanwhile, more than half of governors use The TES as a source of information in their role.
