<%
(‘A’…‘Z’).each do |letter|
this_letter = @schools.select {|school| school.title =~ /^#{letter}/}
%>
<%= letter %>
<% this_letter.each do |schools| %>
<%= link_to h (school.title), new_school_course_path(school) %>
<% end %>
<% end %>

That’s just from memory, but it should work…

Or a little fancier:

<% by_letter = @schools.group_by {|school| school.title[0,1]} -%>

<% ('A'..'Z').each do |letter| -%>
<%= letter %>
<% if by_letter.has_key?(letter) -%> <% by_letter[letter].sort.each do |school| -%>
<%= link_to h(school.title), new_school_course_path(school) %>
<% end -%> <% else -%>
(none)
<% end -%> <% end -%>
