Families with children due to start primary school in September 2015 have until January 15, 2015 to apply for their preferred schools.
Previous years have shown that those who apply late have a 30 per cent less chance of getting a preferred school place, which can be upsetting for both parents and children.
To avoid this, Leeds City Council (LCC) is urging families to submit their preferences by Thursday, January 15, 2015.
Executive member for children and families Coun Judith Blake (Lab) said: “In the last school year, over 400 applications for primary school places were made after the deadline. It’s far more difficult to allocate places in these circumstances and families who do this risk not being able to send their child to their preferred school.
“Unfortunately every year there are disappointed parents and children who we are unable to offer a place to at one of their preferred schools because they apply after the deadline. We want to give everyone a fair opportunity by encouraging everyone to apply on time.
“It’s essential that preferences are made by the deadline on 15 January and that up to five schools are listed - including your nearest school - to ensure every child and young person has the best chance of attending their preferred school.”
Last year 434 applications for reception places were made late. Of those, 158 were unable to be allocated any of their preferences because all of the places had already been filled.
Only 65 per cent of late applicants received one of their preferences compared to 94% of those who applied on time.
Figures for admissions in September 2014 show the percentage of families offered their first preference was 85 per cent while the number offered one of their three preferences was 94 per cent.
The quickest and easiest way to apply is online at www.leeds.gov.uk/admissions. People will then receive their offer by email on April 16 2015.
Parents can also apply using the common preference form, also available at www.leeds.gov.uk/admissions.
Parents using the paper form will have their offer letter sent out by second class post on the offer day so can expect to receive it a few days later.
