I am using KOMA-Script (scrartcl). I am trying to figure out how can I achieve the section formatting similar to this figure.
I found a CV example using res class (CV using res class), but I want to use it in another document which uses scrartcl.
Using enumitem makes for easy adjustment within a regular list (description) environment:
\documentclass{scrartcl}
\usepackage{enumitem}
\begin{document}
\begin{description}[leftmargin=7em, labelwidth=7em, labelsep=0pt]
\item[OBJECTIVE]
A position in the field of computers with special interests in business applications
programming, information processing, and management systems.
\item[EDUCATION]
\textsl{Bachelor of Science}, Interdisciplinary Science \\
Rensselaer Polytechnic Institude, Troy, NY, expected December 1990 \\
Concentration: Computer Science \\
Minor: Management
\end{description}
\end{document}
As @cfr mentioned in a comment, KOMA-Script can do stuff pretty good on its own. Here an example using labeling. You can change the font of the labeling label using the \addtokomafont mechanism. The indent is taken by the length of the argument of the labeling environment. Markus Kohm suggests some further improvements, like putting the \MakeUppercase to a global place. This is nice, since you can change it add one place. Please have a look at the modified example.
\documentclass{scrartcl}
\usepackage{microtype}
\newcommand*{\UpperCaseLS}[1]{\textls{\MakeUppercase{#1}}}
\addtokomafont{labelinglabel}{\sffamily\bfseries\UpperCaseLS}
\begin{document}
\begin{labeling}[\enskip]{education}
\item[objective] A position in the field of computers with special interests
in business applications programming, information processing, and management
systems.
\item[education]\raggedright
\textsl{Bachelor of Science}, Interdisciplinary Science \\
Rensselaer Polytechnic Institude, Troy, NY, expected December
1990 \\
Concentration: Computer Science \\
Minor: Management
\end{labeling}
\end{document}
Little hint: Don't use uppercase, sans serif and bold face.
