ACER ConQuest 4
Purpose: To provide data analysis based on a comprehensive and flexible range of item response models.

ACER ConQuest 4 is a computer program for fitting both unidimensional and multidimensional item response and latent regression models. It provides data analysis based on a comprehensive and flexible range of item response models (IRM), allowing examination of the properties of performance assessments, traditional assessments and rating scales. ACER ConQuest 4 also offers wider measurement and research community analysis procedures based on the most up-to-date psychometric methods of multifaceted item response models, multidimensional item response models, latent regression models and drawing plausible values

  •  •  Estimation of the Bradley–Terry–Luce (BTL) model for pairwise comparisons
  •  •  A choice of marginal maximum likelihood or joint maximum likelihood estimation
  •  •  Fitting of a multidimensional and multifaceted form of Bock’s nominal response model, including its special cases, the two parameter logistic (2PL) model and generalised partial credit model
  •  •  Direct reading of SPSS system files
  •  •  Output of results to SPSS or EXCEL files
  •  •  A wide array of graphical outputs, including Wright maps and Wright predicted probability maps
  •  •  Person fit and residuals
  •  •  Latent variable path modelling
  •  •  Mantel-Haenszel DIF estimates
The ACER ConQuest Version 4 has the following new features:
  •  •  Implementation of multidimensional and multifaceted Bock model and generalised partial credit model (GPCM)
  •  •  Addition of matrix variables
  •  •  Matrix manipulation functions: compute, forif and while commands to manipulate matrices
