A parametric reconstruction of the jerk parameter, the third order derivativeof the scale factor expressed in a dimensionless way, has been discussed.Observational constraints on the model parameters have been obtained by MaximumLikelihood Analysis of the models using Supernova Distance Modulus data (SNe),Observational Hubble Data (OHD), Baryon Acoustic Oscillation (BAO) data and CMBshift parameter data (CMBShift). The present value of the jerk parameter hasbeen kept open to start with, but the plots of various cosmological parameterlike deceleration parameter $q(z)$, jerk parameter $j(z)$, dark energy equationof state parameter $w_{DE}(z)$ indicate that the reconstructed models are veryclose to a $\Lambda$CDM model with a slight inclination towards a non-phantombehaviour of the evolution.
