ABSTRACT
The teachers are the key actors in the effectiveness of secondary school education.

It is therefore important to ensure that they perform their roles as expected towards the achievement of educational goals and objectives.
Descriptive research design was adopted for this study.

There are 702 teachers working in public secondary schools in Ilorin West Local Government Area of Kwara State shall be the target population of this study.

310 teachers was randomly selected out of 702 teachers in the Public secondary schools in Ilorin west Local Government area of Kwara State.
The following are the summary of findings:

There is significant relationship between professional development practices and secondary school teachers’ effectiveness in Ilorin-west LGA, Kwara state; there is significant relationship between attendance of higher education and secondary school teachers’ effectiveness in Ilorin-west LGA, Kwara state; there is significant relationship between attendance of seminars and secondary school teachers’ effectiveness in Ilorin-west LGA, Kwara state; and there is significant relationship between attendance of conferences and secondary school teachers’ effectiveness in Ilorin-west LGA, Kwara state.
Hence it is necessary to do everything that is needed to be done to ensure that this is done. One of the things to be done in order to ensure teachers’ effectiveness is proper staff training. This is because the quality of teachers is enhanced by in-service training.

As rightly said, teacher cannot perform more than their quality, as one cannot give what he doesn’t have. Teachers therefore need to regularly attend training in order to be more effective. Based on the findings of this study, the following recommendations were made, the government should ensure that the teachers of secondary schools are attend training regularly by making provision for them in form of cash.

CHAPTER ONE
INTRODUCTION
Background to the Study
Globally, educating a nation remains the most paramount strategy for the development of the society throughout the world.

It is pertinent to note that many studies on human capital development concur that it is the human resource of the nation not its capital or natural resources that ultimately determine the pace of its economic and social development, the most important institutional mechanism for developing human capital is formal education system of primary, secondary and tertiary training (Nsubuhu, 2003)
Teachers constitute an important factor in the implementation of the curriculum.

The quality of teachers is known to be a key predictor of students’ performance, stressing this point.

Hammad (2001) point out that the simple most important determinant of what student learn is what teacher known.

Teaching as a profession, demand continuous update of knowledge and ability through training programs.

Such training program include workshop conference seminar, induction and orientation for new staff, refresher courses, in-service training and so on.
The examination of professional development programs and teacher effectiveness in Ilorin west local government area public secondary school, Kwara State in these second decade of the 21st century is more desirable with the world population reaching the zenith of 7.3 billion on July 31, 2015 (UNPF, 2015) the public secondary school are more challenged with the complex nature of the increasing diverse population of students given admission from different part of the state without commensurate training given to the teachers for them to live up to expectations and give highest standard of knowledge.
Professional development programs as been accepted as effective method of increasing the knowledge and skill of teachers in order to enable teachers to teach more effectively according to Mohammed (2006) noted that many teachers after graduation have little or no opportunity for retraining and their training ends as soon as they graduate with no opportunity for updating their knowledge and skill by attending seminar, workshops and conferences that will subsequently enhance their knowledge and classroom skills.

Subscribing to this view.Esu (1997) observed that there has been greater awareness that teachers who were trained some few years ago are not adequately equipped for effective teaching except complemented by in-service training.

She further stated that, 2-3 years teacher preparation program in higher institution of learning do not adequately prepare teachers for the teaching job.

As there are too many ground to be covered in the teacher preparation programs.
Apart from challenge of failing standard of education in public secondary school which inadequate professional development program cause to the effectiveness of teachers in secondary school, we should not forget that, regular training of teachers become more necessary when we realize that the future of the country lies with the quality of its teachers.

At least, teachers are the trainers of academics, technologists, technicians and professionals like doctors, engineers, journalist lawyers and accountant.
Hence for teachers to give their best with adequate standard needed within & internationally, more emphases should be place on teachers professional development programs so as to enhance their effectiveness in teaching.
Apart from the fact that first class brains are moving out of teaching profession due to poor remunerations and emoluments, the entry qualification in to the colleges of education are the lowest compared with those for polytechnics and universities.

Also, the improvement of the regular training program for teacher under professional development program scheme become more germane when we realize the need to integrate the new information technology in classrooms apart from the new scientific and technological inventions and innovations in different fields of endeavor.
To take care of the inadequacies of pre-service teacher preparation.

The federal republic of Nigeria (2004) in National policy on education made provision for development of teachers by stating that teacher education shall continue to take cognizance of changes in methodology and in curriculum and that in service training for teachers shall be regulated.

This therefore emphasizes the importance and the need for entry staff to be constantly renewed.

Upgraded and updated in his or her knowledge to be refreshed and to keep abreast with the rapid changing society through professional development programs and effectiveness of teachers.
According to Tajudeen (2008) an aptitude and capacity test was administered for total number of 19, 125 teachers in Kwara State public school in which 2,628 were university graduate.

The teachers were given tests which were designed originally for primary four pupils in English and mathematics.

At the end of the exercise only seven teachers out of the 19,125 crossed the minimum aptitude and capacity threshold. Only one out of 2,628 graduate teachers passed the test 10 graduates score outright zero. Abdullahi (2011) more worrying is that nearly 60 percent of teachers cannot read information or use the information in preparing a simple lesson note.
In view of above assertion, teaching is a life-long learning profession which will demand that teachers should be at fore front of learning due to ever dynamic and changing nature of the school needs. Student needs, societal needs, and development of professional practices. Professional development program and teary school Kwara State should be encourage as continuous process which must last for the duration of the career of committed and dedicated teachers so as to enhance quality teaching and quality learning.
Statement of the Problem
Studies found challenges ahead teachers’ professional development and their effectiveness at school.

Osho (2012) stresses that poor remunerations of teachers affect their professional development leading to the abandonment of their profession, no meaningful intellectual program on the professional development of teachers with the various wars, political crises around the world, the new cultures of gay, lesbianism, and globalization as a form of western model to control the world poses a challenge to professional development of teachers and their effectiveness.

Besides, Amos (2008) expresses that, in spite of desperate need for the effective staff development programs in Nigeria, the caliber of many teachers working in the public and private secondary schools in Nigeria is nothing to write home about because teachers are usually inefficient in the performance of their duties.

Similarly, Ola (2013) states that, the falling standard in the public educational system in Nigeria is as a result of the poor professional development of Nigerian teachers which the government and the teachers must gear up to avert.
Many efforts have been put in place to address the falling standard of Nigeria’s educational systems due to improper professional development program for the teachers.

For example, in Ilorin West Local Government, various professional development program designed for teachers in public secondary school fail and do not succeed.

Similarly, Government and many schools that organize professional development programs for its teachers in the country do have wrong nomenclature that professional development program require placing for people with high potentials in a training program.

Apart from this, the academic performance of students of public secondary schools in Ilorin West Local Government has also being disappointing.

Many students who enroll for West Africa Examination Council (WAEC) and National Examination Council (NECO) respectively in the local government perform woefully.
Indeed, there is an urgent and desperate need for the organization of efficient, effective and up to date professional development programs in the state in line with the best global practice.

Hence, it has been discovered that lack of efficient and skillful teachers have been the reason behind this sordid performance of students.

This study is however imperative in order to investigate the relationship between professional development programs and teacher effectiveness.

This is the gap that this study fills since to the best of the researcher’s knowledge, there no study currently undertaken on this topic especially in Ilorin-west LGA, Kwara state.
