Secondary education covers two phases on the International Standard Classification of learning. 
Oh ok by secondary you mean college?
indeed aand today  Every country aims to provide basic education
Yes that is the least we can do for chlldren
i have read Secondary education typically takes place after six years of primary education and is followed by higher education
Total of sixteen years of education those kids should know  some stuff!
 typically kids enter the lower secondary phase around age 11!
Yes and that is a hard age in getting their attention and keeping them focused in my experience
Yeah education sometimes extends to age 19!  i dont think it is common though
One thing about an education it generally provides tools for better employment and income
