Concern: recommendation for registration in Ashford
X and Y followed the 4th year of elementary school at Royal Athenaeum Yyyyy, Belgium.

At the beginning of the year, some light lacks in arithmetic (fractions and sizes) were detected.
Both of them proved to be excellent in numeration (mental or written calculation). They also have a very good mathematical logic.
I thus think that they would be good pupils in your school in Ashford.
Sincere greetings
