cvrulesspacingvertical
I'm writing a resume and I'm having trouble creating a certain appearance. 
I want to remove that space between education and the \rule. This is the code I currently have written
\textbf{EDUCATION}
\begin{center}
\rule{15cm}{.5mm}
\end{center}
I want it to appear as close as possible to this 
Thanks for the help
To understand the behaviour it is instructive to go to the TeX primitive rules. These are defined using three dimensions height, width and depth:
\vrule height1pt width 1pt depth0pt fjord\par
\hrule height1pt width 100pt depth0pt fjord
LaTeX defines the \rule using these primitives disguised as follows:
\def\rule{\@ifnextchar[\@rule{\@rule[\z@]}} width height raised
\def\@rule[#1]#2#3{%
\leavevmode
\hbox{%
\setlength\@tempdima{#1}%
\setlength\@tempdimb{#2}%
\setlength\@tempdimc{#3}%
\advance\@tempdimc\@tempdima
\vrule\@width\@tempdimb\@height\@tempdimc\@depth-\@tempdima}}
If we construct an example using first the TeX primitives,
\vrule height1pt width 1pt depth0pt fjord
\hrule height1pt width 100pt depth0pt fjord
we get
We get a different behaviour with LaTeX rules as they are typeset in horizontal mode and TeX adds a normal parskip as required..
\rule{1pt}{1pt}fjord fjord fjord fjord\par
\rule{30pt}{1pt}fjord fjord fjord fjord
Full minimal
\documentclass{article}
\parindent0pt
\parskip0pt
\begin{document}
\vrule height0.4pt width 1pt depth0pt fjord\par
\hrule height0.4pt width 30pt depth0pt fjord
\rule{1pt}{1pt}fjord fjord fjord fjord\par
\rule{30pt}{1pt}fjord fjord fjord fjord
\end{document}
The amount of space left is normally lineskip for LaTeX plus \parskip in the examples. vary the parskip value to see how the lines get moved. Note that both start the rule at the baseline of the letters.
Background and explanation
The problem is indeed in the flushend package. This makes the last columns on the last be of equal length, which is a favorable look for some. When a column reaches its full length without flushend it inserts a columnbreak and removes any whitespace.
If this break happens between two paragraphs instead of in the middle of one it removes the space that would otherwise be between these two paragraphs. When flushend does its magic it cannot account for this and the result is two paragraphs with no whitespace between them.
Contacting the author of the flushend package I received the following answer and proposed solution. In short, the 'bug' is due to the order of events. And the solution is to find the column break and add a manual space to match the paragraph spacing between the other paragraphs.
Have you tried something like:
\atColsBreak{\vskip5pt}near the end of document? In the current implementation of the package it is more feature then a bug. At the columnbreak all glue/kern elements at that position are lost during page formating (leftcolumnbuilder). At the end of document is too late get the removed skips.Regards, Sigitas Tolusis
Solution
Add the following near the end of the document and change the size until it matches the other spaces between paragraphs.
\atColsBreak{\vskip5pt}
